Nu Fitness

Fantastic experience: I've been a member at Nu Fitness for six months now, and I still am always impressed with the place. The equipment is modern and is always in good condition, the trainers are consistently correcting form (which was incredibly helpful when I first started weight lifting), and the ambience is electric especially during their spin classes in the evening. The locker rooms are spotless and full of fresh towels, they even have infused water stations. I would highly recommend Nu Fitness to both serious lifters and beginners who are looking for a motivating space to get fit.

Fantastic experience: When I turned 50, I set a challenge for myself: to pursue new goals that would make me feel stronger and more confident. (Let’s face it—weightlifting and protein have become hot topics for middle-aged women lately!) Before training with Doug, I had run marathons but had never lifted more than 10 pounds. In just four months, Doug helped me build up to confidently deadlifting 95 pounds, something I never imagined I could do. Doug doesn’t just focus on form—he keeps you accountable and makes every session engaging and different. Thanks to his expertise, I feel significantly stronger and more empowered. Nu Fitness is in a convenient location and offers validated parking; a huge plus. The gym is well-equipped with a wide variety of machines and free weights, making it a great space whether you’re just starting out or working toward major strength goals.

Fantastic experience: I chose NuFitness after researching trainers online and learning they won best trainers in Oakland and the East Bay. Their holistic approach focusing on longevity, fitness, injury prevention, and nutrition really appealed to me. After two months training with Tim, I'm very impressed. As someone who has trained with personal trainers before, I appreciate that Tim is knowledgeable, patient, and truly listens. He's chill but keeps you accountable, helping you find what works for your body without letting you slack. A perfect example of his expertise: after my first DEXA scan showed lower bone density than I thought, Tim immediately explained I needed to train heavier to improve it - critical insight I wouldn't have gotten elsewhere easily. Highly recommend Tim and NuFitness for anyone wanting a comprehensive, expert approach to fitness.

Fantastic experience: Doug is a patient and great trainer, he has made the process of getting started a lot simpler for me.

Fantastic experience: I've been training with Jenn Romm at NuFitness for the past three months to prepare for my wedding, and I couldn't be more grateful to have her in my corner. From day one, Jenn has made me feel empowered, supported, and genuinely excited about my fitness journey. She's knowledgable, encouraging, and knows how to challenge me without ever making it feel intimidating. I've made noticeable progress since we started and I actually look forward to our sessions -- even the occasional early morning ones. NuFitness itself is a great environment to train in. The gym is private so everyone there is working with a trainer and it's a super focused and motivating atmosphere. Plus the free validated parking in a secure lot is a major bonus for an uptown location.

Fantastic experience: I am 74 and overweight and wanted a trainer who could help me get stronger. Jenn is a perfect match for me. She is so encouraging and supportive and I’m thrilled to feel myself getting stronger every time I come in. One of the best decisions I could have made.

Fantastic experience: My partner and I have been doing 2-on-1 training sessions with Doug, and we honestly can't recommend him enough. I’ve never been someone who enjoys going to the gym, but Doug has completely changed that for me. The facility is great and Doug keeps our workouts fresh and challenging by constantly switching things up, which makes each session feel new and engaging. You can tell he puts thought into how to push us without making it feel repetitive or overwhelming. On top of that, Doug is genuinely a great person to be around. His sense of humor keeps the mood light, even when we’re sweating through a tough circuit. We always leave feeling accomplished and feeling positive.

Fantastic experience: I’ve been training at this gym for several weeks and found it to be a great place! The studio is lively, spacious, and filled with excellent equipment. My trainer, Doug Rae, has been fantastic. He listens to my goals and creates a personalized program that challenges me at the right pace. The exercises and weights he incorporates have been perfect for building my core strength and balance. I’ve seen improvements more quickly than I expected, and I’m keen to keep progressing. Doug is a talented trainer, and I highly recommend him to anyone looking to improve their fitness.

Fantastic experience: Nu Fitness is amazing! Everyone I’ve met—both trainers and clients—is super nice and welcoming. The atmosphere is always positive and supportive, making it a great environment for anyone looking to start or continue their fitness journey. I’ve been training with Nick, and I can’t recommend him enough. He’s incredibly kind, patient, and knowledgeable, and I trust his guidance completely. I always feel comfortable in our sessions because he listens carefully and challenges me in a really constructive way. Thanks to his support, I’m seeing great progress and always look forward to my workouts! If you’re looking for a great gym environment and a trainer who genuinely cares, I highly recommend both Nu Fitness and Nick.

Fantastic experience: I have been working with Doug since December and I have nothing but great things to say about my experience. He pushes me even when I don’t think I could do it and keeps me accountable. I appreciate him doing research on syncing my workouts based on my cycle to make the most of my workouts. I feel so much stronger in such a short amount of time!

Fantastic experience: I’ve been working with Doug for about 2 months now. The process from getting introduced (by the owner Nick) to getting into the swing of things was seamless. I was nervous about going back into weight lifting given musculoskeletal issues/surgery/an autoimmune condition that I have but Doug took the time to understand my health history and goals and set up a program that I’ve really been enjoying. I’m already feeling stronger and safer in the gym.

Fantastic experience: I recently hosted an informational hike with Nick and Nu Fitness in the Oakland Chabot area which was an absolute triumph, exceeding my expectations. Despite it being one of the company's first events of this kind, the preparation and responsiveness to our team's diverse fitness levels and objectives was truly impressive from the outset. The hike itself went smoothly, a testament to their planning. We were consistently engaged by Nick's informative content, sprinkled with delightful fun facts and thorough answers to all our questions. The guides showcased milestone sights, weaving in their genuine passion for fitness throughout the journey. What truly set this experience apart were the unique and insightful reflections on fitness shared by our guide, offering a refreshing perspective beyond just the physical exertion and applying it to our specific office lives. Overall, this hike proved to be an outstanding team-building activity for adults, fostering connection and shared learning in a beautiful setting. We highly recommend this Nu Fitness experience with Nick for any group looking for an engaging and well-organized outdoor adventure!

Fantastic experience: What a find NF has been! Referred from a friend. Nick is the best trainer I’ve ever worked with (only my second haha). Not only is he seriously fit himself and can model totally proper form, he takes a completely holistic approach to training, including being mindful of clients mental, emotional and spiritual fitness. Because it all fits, and he gets it. As a medical doctor I am really impressed with his fund of knowledge of cellular biology, and how it all gets optimized with proper training. He’s all about optimizing a long life health span that’s available to all of us. Very inspiring, and he’s a cool and friendly guy! So is the gym. Small, clean and well thought out, great equipment and changing rooms. I highly recommend Nu Fitness

Fantastic experience: I've been working with Doug for the past three months, and he's been a fantastic addition to my fitness journey. Before training with him, I had very little experience with weight training, but Doug made the transition smooth and approachable. His guidance has not only helped me build confidence in the gym, but I've already noticed a real difference in my strength. Doug is knowledgeable, supportive, and always makes sure my form is on point. I’m excited to keep progressing with his help!

Fantastic experience: Excellent training with a personal approach and touch! I’ve seen amazing results over the last two years of training with Nick.

Fantastic experience: It's been 4 weeks since I stated at Nu Fitness, but its long enough to give Nick, his trainers and the facility a positive review. I spent a few days looking for a personal trainer close to work. After some searches on the Internet and Yelp reviews, I started reading reviews about Nu Fitness and Nick. After some positive reviews, I filled out the form and emailed him. I noted my fitness journey to this point in life and briefly explained what I wanted to accomplish going forward. I found myself in a terrible routine, work 12 hours, then heading to the local breweries for a few beers and dinner. Needless to say this didn't bode well for my wellbeing Looking back over the years, I had gained control of health in my mid-30s, where I lost 40+ pound, gained strength and started running. Running led me to a period in my life that saw me conquer a few 50-mile races. An achievement I never thought I would attempt, hell I never thought I would run 5 miles. Life changed. Priorities changed and slowly I saw everything I had worked hard for slowly slip away. Now age 55, life wasn't getting any easier. I knew I was not very active. I also knew that my daily routine was not one for success. I decided I needed to help make a change in my life, but more importantly to make that change permanent. Previously I joined 24 Hour Fitness (never again) but found too many excuses NOT to go. Sound familiar? Searching Yelp for personal trainers, I ran down a local list in the Oakland/Alameda area. Reading profiles and reviews, checking website, I ran across a trainer, Nick Baltazar. It felt right. I emailed Nick with my story and filled out the form on the Nu Fitness website. It wasn't even a day and I had a response from Nick and we were talking about my fitness journey, where I had been and what I wanted to achieve. He was willing to work with my schedule to get three days of training. After a day of communication with Nick, he connected me with Wyatt. I met Wyatt at Nu Fitness, located at 2345 Broadway, parking in The Hive. Yes, they have easy parking and validation while you are at your session. This makes getting in and out quick and easy. I was highly impressed with the facility, the way Nick had spoke about it, I knew I would be. The work out areas were clean and profession, a small reception area, all Rogue power racks and weights, with room for everyone to work on their fitness goals. Wyatt Berreman, my personal trainer worked with me, after provided basic information from Nick on what I wanted to accomplish. He created a plan specifically for me, tracking my journey, weights and reps for each session. It's been just about 2 months, but its been reestablishing a workout routine. I have a sense of accomplishment, even through I don't see it in the mirror...yet. It will happen. Wyatt has been a wealth of knowledge and has helped create a plan for me to gain strength, balance and flexibility. But also work within my limitations due to previous surgeries on my knee and shoulder. I am very impressed with Nu Fitness, Nick, Wyatt and what they have to offer in the way of personal training. I would highly recommend giving Nick a chance to show you want they can do to help create a fitness plan for to achieve your fitness goals

Fantastic experience: Nick has been a real gem to work with from the beginning. We were searching for someone to work with our teenage son who is not a team sports kid. He was referred to our family by a close friend whose sons highly valued his training. Our son has been motivated by Nick's encouragement, focus and motivation. Nick has helped him develop a workout and taught him a lot about intrinsic strength.

Fantastic experience: Doug has been my personal trainer for the past three months, and he’s been phenomenal. He’s attentive, communicative, and easy to work with. Doug quickly understands your goals and consistently pushes you just beyond what you thought was possible. I feel noticeably stronger and fitter, and I genuinely look forward to our sessions. Nu Fitness is also an excellent gym. It’s fully equipped with top-tier strength training gear, and the location couldn’t be more convenient — just steps from BART with free parking available, which makes getting there completely hassle-free.

Fantastic experience: I’ve been training with Doug for the past five months, and it’s been a great experience. He is professional, knowledgeable, and always brings a positive attitude to every session. His workouts are well-structured, and he takes the time to ensure proper form and technique, which I really appreciate. Since working with him, I’ve definitely seen progress in my strength and overall fitness. I can feel the difference in my energy levels and endurance. Doug has been very supportive and adaptable, making adjustments based on my feedback and goals. If you’re looking for a trainer who is dedicated, encouraging, and committed to helping you improve, I’d definitely recommend Doug!

Fantastic experience: I highly recommend Nu Fitness! Joining a 3-month training program turned out to be the best decision for 2022. During this training, I grew leaps and bounds in terms of my fitness level and also gained a detailed understanding of different exercise modalities to achieve strength and endurance. I can't thank Nick enough for helping me achieve my fitness goals and for the constant positive reinforcement during my training. I returned to the Nu fitness training program after a break of almost 24 months. I had been exercising regularly on my own, but it has been really beneficial to resume training with Nick. I wholeheartedly support Nu Fitness! This training program is not like others. By considering the client's welfare and creating a program that works for them, Nick makes sure they make progress! You can start this program at any level of fitness, and you can be confident that you will finish stronger!

Fantastic experience: Nick is a fantastic personal trainer. He has a great eye for identifying different types of exercises to keep workouts engaging and effective. He also pays close attention to form and provides helpful cues to maximize each movement. If you're looking for a trainer who keeps things interesting while pushing you to improve, I highly recommend Nick.

Fantastic experience: I absolutely love training at Nu Fitness and working with Doug. I started working with him at the beginning of the year to build more discipline and consistency in the gym. Doug took the time to understand my goals and created customized full-body routines. I’m a fairly active person with prior gym experience, I had fallen out of my routine and was struggling to get back on track. With Doug’s guidance, I regained my strength, improved my form, and started seeing results. I also learned a lot of dad jokes - he loves those. His approach is both challenging and supportive! If he see's that you're strong expect to add weight on that squat rack! Loved working with him and how strong I felt after each session. If you are looking for some accountability - definitely work with Doug. This was also an opportunity for me to use gym equipment and not have another person hovering over me because they want to use it too. At Nu Fitness - each trainer has a space/ squat rack area, and mirror where you can workout - there's two other rooms that have additional equipment. Yes, there's other clients, but you won't feel overwhelmed by the amount of people. A few more pluses - validated parking, showers/lockers, fresh magazines in the waiting area.

Fantastic experience: I’ve been working out with Nick for about 8 months and I just cannot recommend him enough. I am in awe of the fitness progress I’ve made with his help — I was pretty out of shape and recovering from an injury when we started, and he helped me recover faster, train to avoid re-injuring myself, and got me to a level of strength and fitness I’ve never had before. Nick certainly knows the ins and outs of training and physiology but the thing that makes me look forward to our workouts every week is his friendliness, his enthusiasm, and how he genuinely cares about me as a whole person, not just my fitness; Nick never makes you feel bad for missing a week, or for being under the weather, or for not being up for something in a workout. His positivity and his supportiveness are what makes Nick a truly great partner in achieving my fitness goals!

Fantastic experience: What I love about Nu Fitness is that each of the trainers--while being fit and impressive in their own way--have friendly and supportive attitude about wellness. They understand that everyone is on their journey, and you can tell that they are emotionally invested in you reaching their goals. I've known Nick as a trainer for over a year now. In that time, I've seen him get so much joy out of the accomplishments of his clients. If you're up for it, he can go deep into the science of longevity and how each aspect of your training sessions will improve the quality of life for the long run. Or, if you just want a decent workout, he'll be there cheering you on as you reach your goals and push your limits. I love the Nu Fitness team, and I believe in the work they do!

Fantastic experience: 2025 and I’m back deadlifting 175# Nick is an amazing trainer with an uncanny ability to make approaches to fitness sustainable, fun, and positive. In the span of six months, I have been more consistent in my showing up for myself through workouts than I ever have in my life. The longest span I've gone consistently was 4 months. I'm so glad to have Nick as a trainer. My health and wellness has never been better and my mindset has also made gains!

Fantastic experience: It’s rare to find a fitness business that truly offers everything you need in one place, but Nu Fitness has it all—personal training, nutrition coaching, and bodywork, all conveniently located in a modern physical therapy office with free secure parking. Like, what?! How cool is that? I was searching for a personal trainer in Oakland who could help me stay accountable and build momentum. As someone who struggles with task paralysis and self-motivation, I needed more than just a trainer—I needed an accountability buddy who could provide both structure and encouragement. Enter Nick, the owner of Nu Fitness. I interviewed a few trainers before being referred to him by a friend, and from our very first consultation, I knew he was different. Nick was incredibly attentive, kind, and thoughtful. He took the time to listen to my goals and asked insightful questions about what motivates me. I thrive on positive reinforcement, and Nick’s supportive and encouraging demeanor made all the difference. What really stood out was the extra support Nick provides outside of sessions. He created a personalized program and a weekly plan that kept me on track between our meetings. This level of care and attention made me feel seen and supported in a way I hadn’t experienced before. I’ve always felt intimidated by male trainers—especially those who seem like they practically live at the gym—but Nick’s approach was welcoming and non-intimidating. He encouraged me to think about performance-based goals to stay motivated, and we decided on achieving my first pull-up. Thanks to his guidance, I reached that goal in just six weeks! Nick is a gem of a human who truly cares about his clients. He’s sensitive to individual needs, never pushy or sales-y, and always comes to each session with my goals top of mind. On top of that, his longevity-focused training philosophy ensures that I’m not just chasing short-term results but building strength, mobility, and resilience for the long haul. If you’re looking for a trainer who will meet you where you’re at, support you every step of the way, and help you become your best self, I couldn’t recommend Nu Fitness more. It’s no wonder they were voted #1 Personal Trainer in Oakland by Oakland Magazine!

Fantastic experience: It's only been a few weeks of training with Nick, and I'm already seeing results. I am more flexible and have better posture, but I'm also stronger and noticing a change in my body/physical appearance already! He prioritizes my goals and works to incorporate full-body exercises + stretches each session. Clearly, he truly cares and goes out of his way to support his clients. He's very intuitive in terms of reading the situation/session (like pushing forward vs. breaking/relaxing), which is helpful. His integration of interesting and fun exercises sets Nick apart from other trainers. I loved our kickboxing sessions, which taught me lots of new moves! It was a great foundation for moving forward. Will continue to use Nick as my trainer and recommend him to others.

Fantastic experience: I had a great experience with Tim as my personal trainer at NuFitmess. I came to Tim to help me build strength in my overall body without aggravating any of my old injuries. Tim was easy to work with, came up with great workouts and knew what to do whenever my body needed a modification. I highly recommend Tim as a personal trainer, he is a gem!!!

Fantastic experience: Doug is the best! I was really nervous to start personal training because I’m heavy, but Doug made me feel at ease. He’s knowledgeable and organized and super encouraging. He’s a perfect cheerleader and pushes me in the best way possible.

Fantastic experience: I use Nu Fitness for personal training and it's been great. Nick helps match you with a trainer who can help you work towards your individual goals. For me, getting older with an autoimmune disease has made me super weak, especially on one side. Having someone come to your home and help you with a routine to build muscle has been more effective for me than PT. I find I am getting stronger each week and building stronger neuro muscular connections -- my primarily goal. If you are looking for a personal trainer, I recommend speaking to Nick.

Fantastic experience: I hit the jackpot with my trainer Billy Salinas. He has his own small gym in his house and it opens to the outside so you’re not with a bunch of people breathing on each other and you get ALL the attention. Billy has changed my life over the last few weeks—I am 65 and this was the year my body seemed to lose it entirely. He’s excellent at figuring out exactly what’s going to help with which body part, and especially at starting where you are, even if you can’t do much of anything. I know he coaches people who are much fitter than I, so I’m sure he’d be great at that too. I highly recommend Billy, and if his talents are anything like the other trainers at Nu Fitness, you can’t go wrong.

Fantastic experience: I have been training with Billy Salinas to address postpartum back pain and to regain my strength for cycling. Not only does he have postpartum training certification, he also has a great attitude and is meeting me where I am at. He’s has an eye for posture and makes minor adjustments to my form and day to day activities that have made a real difference. I literally feel like I am starting from scratch he is patient, kind and encouraging. After 2 months working together my pain is mostly gone and I am getting stronger and more capable! Small wins to be sure, but very meaningful. I would Highly recommend Billy to anyone who has struggles with long term pain, is coming back from injury or just needs someone to help them get back on track.

Fantastic experience: I’ve been training with Nick for more than a year now and it’s been such an amazing experience. He’s an incredible personal trainer who cares about so much more than just giving me exercises to do. He’s an expert and he helps with not just strength, but also food and nutrition, injury prevention, and more. I have come very far and gotten a lot stronger, but the best part is that the workouts always lift up my day no matter how tired I am beforehand. Truve is an incredible spot in Oakland, go train with Nick!!!

Fantastic experience: Tim has been a fantastic trainer for me. He helped me talk through my fitness goals, took my existing injuries into consideration, and crafted a warmup and workout routine that would work with my busy schedule. My gym background prior to this is very nonexistent and working with him has helped me feel way more confident I’m doing the exercises right. My body feels more mobile and stronger each week for both daily activity and for my activities (climbing, dance, hiking). After a few months, I went on a hike with elevation and the usual pain I’d feel my left knee disappeared! Thanks to Nick for helping me feel comfortable starting out and pairing me with Tim too.

Fantastic experience: Tim is a great trainer that is very knowledgeable when it comes to resistance training! I’ve learned a lot of new lifts and have been able to increase my strength vastly. His programs always find new ways for me to push my limits and see muscle growth. Occasionally Tim also implements unorthodox techniques that yield results that other trainers cannot replicate.

Fantastic experience: After a lock-down fitness lull, Nick has helped me get in shape again. Thanks to Nick I’m I’ve got the fitness level of a 40 year old, though I’m pushing 60. He’s the best.

Fantastic experience: I started my journey here a bit nervous and scare. I was introduced to Doug and he made feel more comfortable, real down to earth guy. Took the time and effort and was very patience with me.

Fantastic experience: Update September 2024: Continued working with Nick and now In addition to overall strength conditioning, am also doing longevity training (Strength, balance, and correcting imbalances in my body). We also measure muscle to fat ratio overtime, which is a healthier way to assess progress versus the scale! —- Highly recommend Nick! After only 2 months of individual coaching 2x/week, my posture is better, feel stronger and body fat went down by 2%. Nick customized a program that works for me - Am middle aged and because of some joint issues, my program includes resistance bands and body weight for strengthening. He incorporated stretching during rest periods between sets - perfect for me and getting results! AND we have fun and celebrate progress along the way!

Fantastic experience: Had a great experience with Nu Fitness! It was my first experience with a fitness routine and a personal trainer. Doug did a great job at educating and helped me make great progress. Doug’s chill personality made me feel at ease and relaxed while i made gains. Thanks Nu Fitness, and i look forward to continuing my fitness journey with ya’ll.

Fantastic experience: I've been training with Doug for 7 months and I can't recommend him enough. I first came to Nu Fitness because I wanted to get in better shape but what I ended up getting has been so much more than I expected. Doug's approach is challenging, informative, fun, and I actually look forward to my training sessions, which is something I have never experienced before. He pushes my physical limits and is extremely encouraging in the process, we connect and laugh in between sets, and even outside of our sessions he shares a google sheet where all my sessions are tracked so I can look back and see my progress and/or use as a reference to go work out on my own. 10/10 form me! If you're looking to feel great, look great, and have fun then check out Doug and Nu Fitness!

Fantastic experience: I was never a fan of going to the gym and lifting weights, I’d rather spend my day on a tennis court. However, as I get older maintaining muscle mass is important. I tried following tutorials on YouTube but that resulted in multiple injuries thus my motivation to seek the assistance of a personal trainer. I’ve been training with Tim Nhingsavath for the past three months and the experience has been great. Tim has created training programs that challenge and motivate me while changing the programs periodically to keep things interesting. Most importantly I’m seeing my desired results.

Fantastic experience: I can't say enough about the quality of training I have received from Tim with Nu Fitness. He has been extremely attentive to every rep of every exercise I perform to be sure that I am maximizing the benefit of the work I am putting in and staying both challenged and safe. He has helped me craft a strength training program to help me both recover from a hamstring injury and get me back jogging a few days a week while also keeping long-term overall health a focus. Tim is communicative both in and out of our sessions and such an easy going, quintessential professional. My right hammy and overall spirit is very grateful.

Fantastic experience: Nick is a knowledgeable, enthusiastic and awesome personal trainer. He is empathetic and very sensitive to what I need to get stronger and have better balance. I look forward to working with him every week and appreciate his occasional reminders during the week to help me follow my training program. I cannot recommend Nick more strongly and feel so lucky to be working with him.

Fantastic experience: Doug is an incredible trainer. I’m looking forward to building back my strength and my endurance with him as well as learning proper techniques in training. It’s been 2 months now since I hired him and I’m seeing a progress in my physique. He is extremely knowledgeable and knows how to work physical limitation like chronic back pain and injuries I would highly recommend him to anyone! on top of it all he's a really great guy.

Fantastic experience: Nick has been an amazing trainer to me. He was able to meet me at where I’m at and support me in my goals (training for a half, becoming stronger). I’ve worked with him for about a month or so now and have noticed that my runs are stronger, actually sustainable, and energizing. I’ve also learned how to do pushups and am now tapping into pull-ups with Nick. I highly recommend him! He also provides a program to incorporate into your routine and can give you nutritional advice.

Fantastic experience: I came to Billy because I had started trying to lift heavy and wanted someone to make sure my form was good for safety and longevity. Billy was able to evaluate my movement from a million directions and guided me into correcting technique that I thought was already pretty good. He’s able to speak a language of movement that I understand and am able to apply. I highly recommend working with him if you are someone who values more than just basic fitness - longevity, technique, progress in your workouts, and all the things that will have you moving the way you want to later on in life.

Fantastic experience: Tim is great. I’ve been working out with him for more than a year. He listens and develops workout programs around all of my injuries, aches & pains! I’m definitely stronger and overall feel more fit since I started working out with Tim. I highly recommend him.

Fantastic experience: This was my first experience with a personal trainer. Tim was so friendly, knowledgeable and extremely patient. I think that I will make good progress to my goals with Tim. I would highly recommend any Fitness and Tim in particular.

Fantastic experience: I've been working with Billy during my pregnancy, and I'm completely satisfied!! He has prenatal training and overall a lot of expertise about the body that shows in every session. He is also very kind and enthusiastic. I was having a lot of pain in my second trimester before I started working with Billy, and almost instantly felt a lot of improvement and my third trimester has been so much better. Also, in previous workout situations I've always had issues with knee or hip pain, but Billy helps me adjust to avoid this entirely. I'd definitely recommend him to anyone else who is looking for someone with a lot of expertise, prenatal or otherwise!

Fantastic experience: We work with Nu Fitness to do house calls in our garage – 2 people, 2 sessions each per week. It's an investment, but has made working out with 2 kids under 2 possible again – we're grateful for their flexibility in planning, ability to work with our limited space and equipment, and are excited by the results we're seeing. Have not visited their physical space, but would highly recommend if you're looking for a trainer!

Fantastic experience: I've been working with Doug and Nu Fitness for 5 months. Doug has truly transformed my understanding of strength training and helped me make incredible progress. He quickly assessed my fitness level, listened to my goals, and developed a customized training program focused on teaching me the fundamentals of strength training with a focus on proper form and safety. Doug has an in-depth knowledge of training. He doesn't just put you through random workouts - every exercise has a purpose for strengthening specific muscle groups. Doug makes our sessions enjoyable with his positive attitude and words of encouragement. He genuinely cares about his clients' success. If you want a knowledgeable, results-oriented trainer who can take you to the next level, look no further!​​​​​​​​​​​​​​​​

Fantastic experience: I have been working with Doug once a week for two months now. He did a great job, identifying some areas in my core and lower body that were weak. And by working those areas I have substantially improved my balance. I am a competitive tennis player and this has helped me gain significant control while on the run as well in changing directions, and maintaining strength throughout multiple set matches. He’s a good guy and easy to learn from.

Fantastic experience: My teenage daughter has been training with Doug Rae over the past couple of months. With Doug’s patience and easy going demeanor, she went from being hesitant about working out to someone who looks forward to going to the gym on a regular basis. In this short period of time, she’s quickly gotten stronger, which translated to better performance on the soccer pitch!

Fantastic experience: I’ve been training with Tim for the last couple of months and I am so glad to have him as a trainer. He tailors programs to help with my imbalances and made them flexible so that I had options to workout at the gym or at home. I enjoy my sessions with him and am feeling so much stronger already.

Fantastic experience: I had a great experience with Doug. He tremendously helped me with my squats. No more knee pain

Fantastic experience: I'm SO glad I found Billy to be my trainer. I wasn't able to be active for almost a year (pregnancy & postpartum issues) so my body was in bad shape. From our first session I knew Billy was going to be a great fit. He has a deep and intuitive understanding of how the body works - perfect for helping me on my postpartum recovery journey. After working with him, I now have strength and mobility to do functional movements that I haven't been able to do without pain. And what's crazy amazing is that he's been able to give me workouts that have even started to undo years of damage and weakness in my hips & legs I had before kids. I’ve used trainers before, so I’ve seen a lot of different training methods - I can confidently say Billy is uniquely skilled at getting results. I wish I had met him for prenatal exercises to do preventative treatments, but now postpartum, I'm so grateful that he’s helping me rebuild my core, correct my pelvic tilt, and relieve several chronic hip issues.

Fantastic experience: Billy is really knowledgable, attentive and reassuring. I am proud of the progress I have made and its all thanks to him. Safe to say I'm looking forward to my next session!

Fantastic experience: I have been working with Billy for two months. He carefully assessed my weak points and goals and developed a custom program to improve my overall strength, mobility, injury recovery, and quality of life. He is more of a "movement coach" than a traditional trainer, and is always willing to answer questions about the body, and change the program based on your interests and motivation. I wanted to find someone where I would learn a lot in addition to improving fitness, and Billy is just that person!

Fantastic experience: Billy is one of the best trainers I've worked with. Not only is he incredibly knowledgeable about the body and movement, but he's kind and meets me where I am. I've never before experienced a trainer who is more interested in my well-being than in making me fit some idealized version of what "healthy" looks like. And that's not to say that I don't get a great workout with Billy. Quite the opposite! Both our work in session together and his programming for me to do on my own have me feeling stronger and more balanced than I have in years.

Fantastic experience: After a severe infection that left me with a number of chronic conditions, I had stalled out on making progress toward my mobility and health goals. I undertook kambo as part of my healing journey and the practitioner recommended Nu Fitness. My initial call with Nick (owner) was very detailed, and he was an attentive and validating listener. I was matched with Doug (trainer), who has been wonderful. We have been working together for about 4 months, and I am definitely more able to do basic life tasks without exhaustion (which was my goal). I even have a (tiny but growing) bicep muscle now! I have a number of challenges that make workouts a little more complicated, and Doug is always warm, supportive, and motivating. He goes out of his way to create workouts that are tailored to my needs and respect my limitations but does a great job motivating me to push through challenges as well. He has a particular knack for being in tune with when I've pushed myself too far before I do. All-in-all, Doug creates a safe, welcoming space in the gym, and I would wholeheartedly recommend him no matter your fitness goals.

Fantastic experience: Working with Billy has been life changing. Billy's thoughtful approach and attention to detail make every session personalized and effective. His ability to push you while ensuring your safety reflects a perfect balance that sets him apart as a dedicated and caring personal trainer. If I could, I would train with him every day!

Fantastic experience: Nick is super knowledgeable and encouraging- helping me to get stronger and ensuring I’m keeping my joints safe with good technique and multiple options to keep me motivated. Thank you!!

Fantastic experience: Nu Fitness is amazing! I started training eight Doug 6 weeks ago and it’s completely changed how I workout. Doug is super patient and super knowledgeable - I feel like I learn something new about the body every session. Highly recommend Doug and Nu Fitness to anyone looking to get serious about their fitness.

Fantastic experience: Training with Doug at Nu Fitness was great! He worked around my limitations and was extremely conscientious in how he structured his sessions. Doug is knowledgeable, kind, fun, and committed to being the best trainer he can be. Doug pushed me in the best possible way, ensured I was using proper technique, and gave me tips I could incorporate in my workouts outside of the studio. Highly recommended!

Fantastic experience: I had a great experience with Nu Fitness and Training with Doug. Doug listened to my goals and knew how to push me so I could accomplish them. He was also a great communicator and was there for me any time I had questions about our workouts.

Fantastic experience: I would give Nu fitness 10/5 stars if I could. I’ve been working with Doug for just over two months and I am blown away at the differences I can see already. Doug is prompt but flexible, professional and personal, and most importantly, he tailors your program to your exact needs. After years of dealing with an injury, I feel confident in the gym for the first time in a *long* time. Looking forward to continuing to grow with Doug and Nu!

Fantastic experience: Doug has been great! Very good at programming around and to fix injuries, which has been incredibly helpful. Also very flexible with adjusting to days where injuries are acting up. Overall has been a great experience.

Fantastic experience: Coming off of a long period sidelined with an injury, and working back to regular exercise post-PT, this has been super helpful. Doug's done a great job finding a set of exercises that work, and navigating the various imbalances etc that are lingering from my various injuries. I'd absolutely recommend, he's been great all around!

Fantastic experience: I highly recommend Nick and Doug for training! They really focus on creating a unique plan for you and slowly working up to your ideal goals. Very encouraging and knowledgable group of trainers in a supportive, no judgement, space.

Fantastic experience: This review is for Billy who I started training with a few months ago. I have struggled with finding the time to workout, exercising/building strength while managing previous injuries, and also just knowing what to do. Billy has been incredibly welcoming from the start, and he is extremely knowledgeable about body mechanics which is exactly what I needed! I trust Billy completely in his assessment and plan for our sessions. In just a few months he has helped me build strength while managing my previous injuries. He helps me work on muscle groups that I have previously ignored. Every workout is specific to my body and my needs and it has been really awesome to have that kind of guidance and has helped me so much! He puts a lot of thought and care into our sessions and it shows, and I’m really happy to have found him here in Oakland. I couldn’t recommend him enough!

Fantastic experience: Nick is excellent to work with. I highly recommend working with him. I've never worked with a trainer before and was a bit intimated by it. Nick met me where I was and helped organize and correct my years of self-taught weight lifting by sharing his incredible knowledge of and enthusiasm for physiology.

Fantastic experience: Nick is the best, I really love training with him. He is such a genuine person and he really knows how to motivate me to hit my fitness goals. I came into Nu Fitness as an already experienced gym goer but Nick has shown me a ton of new workouts that I wouldn't have ever been exposed to otherwise. He has helped me address a number of imbalances I was dealing with and now I'm feeling stronger and more mobile than even. I'm happy I decided to start personal training with him!

Fantastic experience: I had been training by myself for a year before reaching out to Nick for personal training. (My goal was to do my 1st unassisted pull-up.) I wish I had done so sooner! Nick is an amazing personal trainer. Committed, focused, great technical command of movements/exercises and really does take the time get to know you and your fitness goals. Provide an emotionally safe space to get strong and get fit! Sometimes you need a coach to really accelerate your progress--and Nick the perfect personal trainer for the job.

Fantastic experience: I honestly just love Nick! His ability to be contradict the terrible things that I say about my body and progress is so healing. I look forward to not only our physical workouts but also I look forward to how I will feel when I leave his presence. I’ve never had this experience before and for this alone, I will be a forever client. :) Just recently I added my son to his clientele because I believe wholeheartedly that he will not only take care of your physical health goals… but you will walk away feeling like the world isn’t such a bad place. :)

Fantastic experience: Nick is a fantastic personal trainer! Whatever your fitness goals are, Nick will help you make progress. He has a deep knowledge of exercise physiology, and a customized approach to training. I used to dread exercise from a history of sports injuries and I was looking for someone to help me train pain free. Nick tested my strength and mobility to customize my exercise program allowing me to workout pain free for the first time in years. In two months I’ve gotten stronger than I ever expected, I can workout pain free, and I’m back to loving physical activity.

Fantastic experience: Nu Fitness is an amazing space full of knowledgeable people who specialize in physical therapy, Pilates, personal training and much more. I have fitness goals that I want to achieve and I reached out to Nick Baltazar. Nick is truly an amazing person and trainer. He is attentive and passionate about fitness, and cares about all his clients. He makes training fun and really finds what works for you. I haven’t trained w Nick long but I already feel stronger and I can’t wait to see what else I can achieve w his help. He is truly great at his craft and I highly recommend him if you have any fitness goals you need help with!

Fantastic experience: Nick Baltazar infuses every ounce of passion, energy, and drive for personal training into all facets of his business. His mission is to help you exceed your personal fitness goals and be the best version of yourself. Nu Fitness was founded on the principles of positivity, supportiveness, inclusiveness, and personal well-being – and he remains true to that vision every single day. I was originally connected with Nick and Nu Fitness through my wife, who has been training with Nick for many years with outstanding results. I have never worked with a personal trainer before, but I’m an avid tennis player and all-around athlete. When an ankle injury sidelined me from tennis for several months, it was the perfect opportunity to incorporate a fitness routine into my daily life. Enter Nick and Nu Fitness…what an amazing gift for my recovery and strength training! Nick is a great listener and is extremely attentive to my fitness needs. He thinks strategically and has crafted the perfect plan to get me back on the court safely. With my newfound balance, strength, and mobility, afforded from our training sessions, I’m now playing some of the best tennis of my life. I’m certainly planning to train with Nick well beyond the scope of my injury. I’ve already learned so much about fitness. And, at the end of the day, I feel stronger, faster, and more agile than I’ve ever felt before. I would highly recommend Nick, in addition to, any of the Nu Fitness programs. The training is holistic, methodical, science-based, and most of all…fun!

Fantastic experience: Nick is transforming my teenage son's life. My son is athletic but uninterested in competition, so he has disliked the experience of school and extracurricular sports programs. Even solo sports that he used to enjoy, like rock climbing, seem to eventually gravitate towards competition. While working out with my own trainer I watched Nick coach and train clients for nearly a year and was always impressed by him: his focus as well as warmth, his attention to form, his own modeling of well-balanced musculature (whole body! core strength!), and another important one to me...the absence of a big ego. : ) I finally got my son to come in and try a session and watched Nick connect with him in the first minute of conversation! So smart. My son son soon asked to work with him twice a week. He continues to look forward to every session and come home smiling and energized. Miraculous to us, from one who used to argue with us to avoid exercise!! He speaks highly of Nick and has enjoyed the way Nick teaches him about anatomy and biomechanics. In fact, out of their work he has even discovered a passion for drawing the human body! (He's an artist but never had an interest in drawing real people.) His mood has become consistently upbeat, his appetite has grown and his body has quickly developed incredible tone. Most importantly, he seems to feel great about himself! He stands taller and has a new bounce to his step! Nick is dear to us and I am eager to recommend him to any adult or teenager of any gender. Why learn from anyone less than awesome? And he is awesome in so many ways! Thank you with all my heart, Nick! You deserve every success and will thrive! We love you!

Fantastic experience: My personal trainer Tim is amazing. I initially started with a personal trainer to build up lower back strength and balance for an upcoming performance but the all the positive changes, increased strength, and self confidence I've felt has me continuing my fitness journey nearly 10 months later. Tim is very knowledgeable, with a calm understanding demeanor while still able to motivate and push you further. I highly recommend Tim, Nick, and everyone at Nu Fitness. Life changing.

Fantastic experience: I never thought I could enjoy training this much! Nick and his team have cultivated an amazing fitness community- this social component to exercise is really motivating, especially in this post-lockdown climate. I got my routine back, hit my fitness goals of feeling strong and feeling good, had fun, and made friends in the process. Nick and his team are welcoming, friendly, knowledgeable, encouraging, and excellent teachers. I got a custom and unique program built for me and Nick programmed what I should be doing outside of sessions on my own every day of the week! In our sessions I can’t help but find myself smiling and laughing, while simultaneously dripping sweat! If you want to get your fitness routine back on track, reignite your passion for being active, or just level up your current state of fitness, Nick is your trainer!

Fantastic experience: Nick is incredibly organized, sincere, and passionate about his work. I’m excited to continue to build relationships with him, his team, and clients. I look forward to accomplishing more meaningful work together.

Fantastic experience: I found Nick on Yelp with the goal of toning up through strength training workouts. I am so glad I did! He is incredibly kind and humble, listens to your goals and is always encouraging with a positive attitude. He built out a custom workout plan for me and helped me set new goals when we crushed the old ones (hello plyo-push-ups)! While looks aren't everything, I do have his training to thank for my newly visible six pack. If you need someone to motivate you, guide you, and cheer you on every step of the way, Nick is the perfect trainer!

Fantastic experience: billy is the best!!! have been working w him for 6 months and have seen so much improvement

Fantastic experience: Training with Nick has been one of the best things to happen with me. He's such an amazing and caring coach and I am always happy to work with him. His holistic approach to training and health keep me motivated and I love how genuine of a person he is.

Fantastic experience: Passionate, knowledgable and thoughtful best describe Nick's approach to personal training. He's helped me work around injuries, strengthen the core, improve posture, and increase overall strength. Nick also builds plans for non-training days, to help make sure you stay on course to achieve goals. Really a great all-around experience, and I would highly recommend Nick and his team of trainers.

Fantastic experience: As an owner of a physical therapy practice, my team of Physical Therapists has been able to witness the great work that Nick provides for his clients. We would trust sending Nick patients of ours once they have completed their work with us to ensure that they continue to remain pain and injury free! Highly recommend Nick!

Fantastic experience: Nick is the best personal trainer I could ever asked for! My husband and I met Nick around August 2021 and he made us feel so comfortable from our very first session. Nick took time to learn about our fitness goals, taught us many different exercises, and even sent us work-out videos to do at home (on days when we don't meet.) At that time, we hadn't worked out in a long time thus we were a bit nervous to start; but Nick made sure to customize a program for us to follow and built ourselves up over time. Also, Be ready to have a lot of fun! His positive energy and smiles are really contagious.

Fantastic experience: Nu fitness has been super helpful for my fitness goals. I’m a yoga instructor, cyclist, and runner, and sought out personal training as a way to even out imbalances from years of activity and some major injuries (as well as some bad habits). Tim is my trainer, and has been SUPER HELPFUL in this process. He built me a very tactful program targeting my goals, and my yoga practice & other areas of activity improved well beyond expectations. Within just a month of training I noticed significant strength gained in my shoulders which really helped in improving my yoga inversions (finally got a fore-arm stand, yeah!) Aside from helping me achieve my fitness goals, Tim has been so welcoming, friendly, and nonjudgemental that I’ve felt really comfortable in our sessions. He’s made strength training very approachable, which I had always felt intimidated from in the past. 10/10 would recommend!

Fantastic experience: I'm so glad I took the leap and started training with Nick! After feeling lethargic from months of staying at home during the pandemic, Nick helped jumpstart my return to fitness. He's been so enthusiastic and supportive, while also meeting me where I was as I got back into an exercise routine. He makes workouts fun, encourages making fitness goals and develops plans to achieve them. Thank you, Nick, for your support on this journey (and for helping me reach PR after PR)!

Fantastic experience: Nick at NuFitness was my trainer for 5 months and I had a great experience, 5 stars, I highly recommend. As things opened up from the pandemic it was hard for me to get back into an active lifestyle but Nick put together a program that set me up for success. I would say Nick’s training style is best suited for people who want to achieve greater performance and wellness that is sustainable, versus aggressive lift goals, though I’m sure he can do that too. His philosophies are more about building a mind-muscle connection and ensuring the right muscles are properly engaged before lifting heavy. Perfect for me in my fitness journey. Nick trains most of his clients at Truve in Oakland. It’s a small gym that provides TRX, free weights, squat racks, stationary bikes, benches, etc. The locker rooms provide towels and showers, and you get free secure parking behind with your sessions. If you’re looking for highly specialized equipment, there are bigger gyms with more variety but at Truve all of the basics for a great workout are covered. Nick has done an amazing job building a fitness community amongst his clients, which further reinforced adopting an active lifestyle. Nick plans bike rides, hikes, slack lining, Spartan races, etc. for all of the NuFitness clients so you get the chance to meet new people and participate in weekend activities rather than defaulting to couch potato activity. I found this reinforced my fitness progress and helped me see my results in the real world. In summary, I was able to achieve my goals to do pull ups, hand stands, and squat my body weight in 5 months through Nick’s program and training philosophies. I highly recommend NuFitness for other people who have wellness goals and want to achieve a more active lifestyle to supplement work from home or post pandemic habits.

Fantastic experience: Nick is great! I’ve been training with him for awhile now and he always makes it fun. I feel like I’ve gotten so much stronger!

Fantastic experience: I have been training with Nick for the last couple of months, and I wish I had started training with him sooner. Life changing! I’ve made so many gains not just physically but also mentally. Not only has my BF% been steadily decreasing and hitting lifetime PRs, but more importantly, I am addicted to working hard and having fun at the same time. What’s more, I get structured coaching, focused attention on form, personalized programming, precise feedback, answers to my many questions, and a heck of a lot of support. I’ll be bummed that I can’t continue training with Nick when I move back to the East Coast, but it was always our goal that I build a solid foundation so that I can continue on my fitness journey beyond my training with him. I am deeply indebted to him and hope I can find a trainer with a similar background, philosophy, and training style. I highly recommend Nick and his team for personal training. It’s truly an investment in yourself, and future you will thank you.

Fantastic experience: Major results & non-stop laughs After a tough year that left me with little motivation, Nick made getting back on track a blast -- and his plan accelerated my results way beyond my expectations. I've gained 5lbs of muscle in 9 weeks, my endurance is at its best and I'm really enjoying the Truve community.

Fantastic experience: I can’t recommend Nick enough! My fitness isn’t something that comes easy to me. I wasn’t the kid who was picking up a football and tossing it around with my dad. As I grow in my body I have always struggled with fitness, movement, and growth. I started working out with Nick about 6 months ago and my attitude towards training and fitness has been transformed. Nick has been such an amazing inspiration for me to achieve my fitness goals as well as my life goals. He’s helped me realize the connection between my personal and professional life. I look forward to each and every training session together regardless of how hard the work is. In fact I look forward to the hard work now - where I haven't before. His excitement and energy is contagious. I’ve worked out with other trainers and what I like about his approach is that we’re always doing something new. He’s finding different ways for me to achieve my fitness goals rather than repeating the same exercises. Whether I’m maxing out my pushups with someone on my back or pulling someone around the gym on a sled it’s always different – and often times fun! I'm stronger than I've been before, and definitely seeing the physical results. Looking forward to what I can achieve next!

Fantastic experience: Nick has such great energy. He's a really encouraging trainer. Nick's HIIT workouts are challenging and fun. He's really knowledgable and I'd recommend his training to any of my friends!

Fantastic experience: Nick is definitely the trainer you want in corner if you are looking to take serious steps to improve your overall fitness level, as well as to build a solid foundation of healthy lifestyle habits. At my last check-up, I was told that my cholesterol and A1C levels were elevated compared to my pre-pandemic numbers. They were not yet in the danger zone, but at 64 years old with a family history of heart disease and diabetes, I took this news very seriously. However, I found myself needing direction and help setting reasonable fitness goals. Nick gave me all that and so much more! He helped me stay on track with positive reinforcement, checking in with me outside of regular training sessions to keep me accountable, and guiding me through rough patches with his incredible uplifting attitude. His energy is contagious, and I feel he is genuinely invested in my success. We recently celebrated my having lost 20 lbs. in 10 weeks, but the journey has just begun. As Nick says, it's all about consistency! I highly recommend Nick if you want somebody who will teach you and motivate you, keep you accountable without being judgmental, and stick with you through the highs and lows on the path to your individual goals. I feel fortunate to be working with him.

Fantastic experience: Nick.is super knowledgeable, friendly and really enjoys helping people. He has helped me add things to my routine that have been hugely beneficial. I regularly do bootcamp workouts with him as well as HIIT classes and other mobility and Strength training. He is definitely more like a fitness professional than a gym shark and you will feel at ease no matter what level you are. Meaning great non-judgemental energy

Fantastic experience: As a long-time daily exerciser, I don't often seek outside advice for training. I tend to be stuck in my ways & like to stubbornly do my hour on the stairmaster + weight training circuits I designed myself. Nick is the first person to get me to try other modes of working out, & for the first time I was motivated to actually do an entire HIIT workout. Nick designed a glute-focused HIIT routine for me as glutes are my area of focus, and went through the entire 30-minute workout with me. After 17+ years of daily workouts either in the gym or on a hiking trail, this is the first time I've appreciated that I can get a satisfying workout in the comfort of my home/backyard/basically anywhere. Nick took me through the HIIT moves & routine, and also provided helpful cues to alter my positioning in order to make the moves more effective & prevent injury (he taught me to do something called the "draw in" maneuver). I'm still a stairmaster devotee, but with my busy schedule & long hours in the hospital, sometimes the gym is closed/isn't an option. I'm extraordinarily grateful to finally have alternatives (that I am actually motivated to do) to get my daily cardio fix in novel ways. In addition to the HIIT routine, Nick also designed a great spin class circuit that we did together, and continues to provide me with other types of support and motivation to incorporate things like stretching, balance, foam-rolling, and other things I tend to neglect or don't want to spend time doing. Finally, Nick spends time pouring over research and content from renowned personal trainers and physical therapists, and really knows his stuff. He understands the body and fitness at a deep level, and is constantly sharing new information that is super helpful in building a well-rounded fitness regimen. If you're looking for ways to mix up your training or just starting out, you definitely will not regret investing in some personal training with Nick.
