Jenn is always walking around and helping throughout the work out, she is also a trainer that actually can do everything they ask of you!! The work outs are set up for you, there are several classes available M-F, and you can always count on Jenn and other members to push you. Can’t recommend this gym enough, it is the BEST!!!

Fantastic experience: I’ve been a member here for almost 6 years, and I can honestly say this gym has been one of the best investments I’ve ever made in myself. From day one, the atmosphere has always been welcoming, motivating, and genuinely supportive. This gym is truly a community, and over the years it’s grown into something that feels like family to me. That kind of environment is rare, and it makes all the difference. I’ve seen real results not just physically, but mentally too. It’s more than just a gym, it’s a place that keeps you coming back because of the people and the support. Grateful for nearly 6 years of consistency, growth, and encouragement. Highly recommend to anyone looking for a place that actually delivers.

Fantastic experience: I haven’t worked out in over a year and came to Jen and her classes and honestly I love it! I’ve been here for a month and I already feel stronger. She definitely works out muscles I didn’t know I had lol and the environment is awesome! I have brought two of my friends with me and they also love it here! Definitely recommend!

Fantastic experience: I’ve been coming to Master Trainers of California for about 7 years now, and it has truly been one of the best decisions I’ve made for my health. Over the years, this gym has helped me stay consistent, strong, and confident at every stage of my fitness journey. The workouts are always well-structured and purposeful, and I’ve learned so much about proper form, strength, and taking care of my body. It’s a place where you feel guided and supported every step of the way, which has made a huge difference for me over time. What I appreciate most is the consistency and sense of family here. It’s not just a place to work out it’s a place where people know you, support you, and keep you motivated to keep going year after year. I highly recommend this gym to anyone looking for a supportive, results driven environment that you can stick with for the long run.

Fantastic experience: The best of the best!

Fantastic experience: I’ve had a great experience at Master Trainers of California. The environment is very motivating and welcoming, whether you’re just starting out or already experienced.

Fantastic experience: Great Environment, Great People and best part I can take my kids. Updating my review. Still a great place and environment, I followed the plan and gained confidence and lost some weight. Thank you!!

Fantastic experience: I joined MTC last march for the challenge I’m so impressed with the results; Thank you Jen for make us feel like home. If you trying to find a gym where you can take your kids this is it; Kids cave keep your them entertained and you won’t have no EXCUSES to workout! I love MTC!

Fantastic experience: I’ve been going to this gym for over a year and a half, and I can honestly say it’s been such a great experience. Jen is an amazing trainer—super helpful, supportive, and always willing to meet you where you’re at. What I love most is that it’s truly for anyone, no matter your fitness level. You can go at your own pace without feeling judged, and everyone there is friendly and willing to help, which makes a huge difference. Life gets busy, and as a parent, it’s not always easy to make time—but being able to bring your kids if needed makes this place even more special. If you’re looking for a welcoming, supportive environment to get stronger and feel better, I highly recommend it!

Fantastic experience: Jennifer is an incredible trainer and truly one of the best parts of this gym. She holds you accountable while still being encouraging and supportive, always pushing you to work harder and keep going even when it gets tough. Her workouts are great, constantly changing, and very diverse so you never get bored. The environment at this gym is also amazing—very positive, welcoming, and supportive of people at all fitness levels. Whether you’re just starting out or more experienced, you feel comfortable and motivated here. Highly recommend!

Fantastic experience: Fantastic Bootcamp! Jennifer, Freddy, and all the staff really care about making sure you are safe while building up your strength and getting a great workout!

Fantastic experience: The best gym, ever! The atmosphere, the people, the challenges—everything about it is amazing! It’s changed my life in more ways than one. Thank you, Jen!!!

Fantastic experience: After having my first child, I felt lost trying to find the right gym. Master Trainers was recommended to me & the moment I walked in I instantly knew I had found my place. Jen (the owner and trainer) truly cares about her clients and helping them become the best version of themselves. She and the other members are incredibly encouraging and push you to challenge yourself and realize how strong you really are. What also sets MTC apart is the focus on proper training. Rather than just moving everyone through a workout, the trainers take the time to correct your form and make sure you're engaging the right muscles. That attention to detail helps prevent injury and makes the workouts much more effective.

Fantastic experience: I originally started master trainers after having my son in 2020 to “bounce back” from pregnancy and absolutely loved it because I could bring my baby with me. We moved away and then moved back after having my daughter in January of 2025 so I started back up again on my postpartum journey and have been going almost continuously for 5 days a week since then. The community at this gym is absolutely amazing. Everyone pushes you to be a better version of yourself, Jen included. She’s so knowledgeable and helps give you that extra push when you don’t think you have anything left in the tank. I love that I can bring my daughter with me to the gym everyday( for free) If you’re looking for a gym to help motivate you, friendly people, bring your kids with you and a kick ass trainer, look no farther!

Fantastic experience: This place absolutely changed my life for the better! Has been my gym since 2022 & it has been the most consistent thing in my life! The trainer Jen’s amazing with her approach to motivating, teaching & how she genuinely cares about her clients! Workouts are great I was even able to modify & continue working out throughout my pregnancy with the help of modifications & support! Atmosphere is welcoming & super supportive! Definitely a family friendly place! Highly recommend!!

Fantastic experience: I was never a “gym person” I had never even had a gym membership before Master Trainers. That completely changed once I started coming here. Every class leaves you feeling stronger both physically and mentally, it honestly feels like therapy. The community is amazing and the early morning workouts are the perfect way to start the day… and that’s saying a lot because I was never a morning person before this! I’ve been out for about a month due to an injury and I can’t wait to get back. That’s how you know it’s special, I actually crave the workouts.

Fantastic experience: This gym is amazing! I joined a couple challenges and not only were the workouts user friendly but the way she focuses on building workouts for all experience levels and that will challenge everyone who walks in the doors.

Fantastic experience: Wanna loose weight? Gain muscle? Build long friendships? This is YOUR PLACE to be!!!!!

Fantastic experience: Great atmosphere! Good music and shes a great supporter of the community. Builds great (family) bonds

Fantastic experience: Jenn is so patient and understanding. Family friendly

Fantastic experience: Great small gym with such a friendly vibe! The boot camp workouts are fun and challenging, and everyone is really welcoming. Definitely a great place to get a good workout in especially during challenge season (my personal fav)

Fantastic experience: If you’re looking for a gym that will help you get results this is it! Jenn is an amazing coach! She is straightforward and is not playing games with your fitness journey. I have a few months attending and so far I love it! I have seen results even over the holidays! Jenn will provide you with fitness and nutrition guidance that is personalized to your goals! Overall, the one thing I hate is that I didn’t join sooner! ❤️

Fantastic experience: Master Trainers is a great place to train! The trainer Jen is awesome! The atmosphere is great, and it is kid friendly! Highly recommend!

Fantastic experience: MTC is amazing ! This gym has helped me find myself again and I’m so grateful! I’ve gained self confidence and some amazing friends along the way . I’ve never enjoyed going to the gym , I always felt out of place because I had no idea what I was doing, but not at MTC. All you have to do is show up- everyone is so helpful. This place isn’t just a gym, it’s family .

Fantastic experience: Absolutely love this place. My son first started going here a few years ago building his confidence and helping him understand what his body needs and what it doesn't. Jen provided meal plans to help him as well as me with understanding what he needed. I then personally joined as well and Absolutely love it the people the environment and being able to also bring my youngest when needed. Master trainers is perfect for all age groups.

Fantastic experience: My husband and i have join MTC in January 2026 and we are are just loving it , not only that everyone is nice and welcoming, Jennifer is super nice and always looking out for her members and coaching how to lift or form correctly. MTC has made a big difference in our lives and we are feeling better then ever ! Thank you Jennifer

Fantastic experience: I was looking for a knowledgeable trainer, friendly atmosphere & a thorough, challenging workout and that is exactly what I found at MTC. Jennifer is encouraging, down to earth and motivates you to do your best. I love the consistentcy in the schedule - we always know which muscles were targeting each day of the week. I also enjoy the variety of the workouts- we're always targeting muscles in new ways so I never feel bored. So glad I found a gym that I look forward to going to each day!

Fantastic experience: Walked in 7 years ago and NEVER looked back. May have took a break here and there due to life but, continued to come back everytime and it was always with open arms. Jen truly is a trainer that you need in your life. She understands the mom life, working, late nights, the struggle and she continues to help motivate people. The best trainer to text about meals, not feeling with it, feeling shy. .she will always get you back on track. No other bootcamp has this same energy.

Fantastic experience: The best place to get back on track and stay there! Love the people we get to work out with, love the motivation and the positive accountability. A gym that’s turned into family and welcoming to everyone. Children feel at home and moms can get back on track! Jen has supported so many people through all different seasons of their lives. Will always recommend her gym to everyone that needs a change in their life! Stop in and try and class, I garuntee you won’t look back.

Fantastic experience: MTC is my second home! When I first joined I had never worked out before but Jen (the trainer) and other gym members helped so much! Jen makes sure to help with proper form and any modifications you might need. She’s helped challenge and push me to lift heavy and helped me see what I’m capable of! I enjoy all the different workouts and the option to come to one or multiple classes in one day. There’s also a kids area which was great for me when I first started and would bring my daughter. I recommend MTC 100%!

Fantastic experience: Best gym ever! So welcoming.

Fantastic experience: I am beyond thankful that Master Trainers was recommended to me! After having kids, I really struggled to get back into my gym routine, but joining this gym almost two years ago has been one of the best decisions I've made for myself. Jennifer is an amazing trainer who truly pushes you to do your best, while making every class fun and enjoyable. Her energy and support have made a huge difference in my motivation and confidence. When I started I felt very welcomed and supported. I now consider this my gym family. Even my kids love coming here and it is nice to see they are having fun and making friends while Mom gets a great workout in! I highly recommend Master Trainers to anyone looking for a supportive, motivating gym environment!

Fantastic experience: Best gym in Modesto! A community that supports and encourages each other to get your heart healthy!! It is also kid friendly!!

Fantastic experience: This gym is unlike any I have been to, it’s family friendly so you can bring your kids while you get in a great workout. Jen is awesome and is always coming up with new stuff to challenge you and make a great workout!

Fantastic experience: This gym has changed my life for the better. I was struggling as a new mom. Not being able to have someone watch my child consistently so I can work out and trying to find a place to work out that I didn’t just have to drop off my child (mom guilt I tried and he cried the whole time). I was offered a free class. Started the challenge. Fell behind for health reasons. Waited for the next challenge stuck with it the best I could and now I am signed up. Staying consistent is my goal. Already my mood has gotten so much better, the amount of energy I have has increased, and overall just grateful I found this place. All the moms are amazing and kind. Best part the owner is a Mom and understands the struggle.

Fantastic experience: Daniel and Jennifer are amazing people and have a beautiful family. If you want to change your life and have the right motivation for you to succeed your goals, I highly recommend them and their business. 10/10 the best around.

Fantastic experience: Love MTC aka Dannifer and all the peeps I get to workout with you won’t be disappointed

Fantastic experience: I tried out the 4 week promo for $75 and I was hooked. I've been with MTC for 7 months now. I have notice so many different changes and I was getting stronger. Jen and Dan are amazing trainers. They have helped me tremendously with my posture and pushing me to my limits. I highly recommend MTC!

Fantastic experience: My husband and I have tried multiple gyms and boot camps in the last but nothing compares to MTC!! Jennifer and Daniel are a dynamic partnership that brings fun, encouraging and challenging workouts each day!! I highly recommend!

Fantastic experience: I am so glad I found Master Trainer’s! Daniel and Jennifer have been nothing short of amazing with helping me transform physically as well as mentally. Most recently I lost 30lbs in 8 weeks during their biggest loser challenge for 2018. They have pushed me way out of my comfort zone and instilled confidence in me in a way I never imagined. Come try and see for yourself, 1st class is free! There is no comparison between MTC and other bootcamps. This place is a family atmosphere with great positive energy. Love MTC !!!

Fantastic experience: Jen and Dan were very welcoming when I was a newcomer and even now. They pushed me when needed and allowed me to make my own best judgement if I felt certain workouts or weights needed to be adjusted based on my body and needs. When I found out I was pregnant they modified workouts to benefit me and the baby. The workouts are challenging and I always leave in a better mood. Thanks for all you guys do!

Fantastic experience: These amazing trainers create a fun and welcoming environment all while getting fit! Best decision I made crossing over to the #dannifer side. If your looking for a gym come try it out !

Fantastic experience: Although there is many boot camp style gyms around, I am so glad I chose Master Trainers of CA. The trainers, Jennifer and Daniel are really down to earth and knowledgeable. Everyone is so welcoming and you don’t feel judged. I originally joined as part of a challenge, but since then have decided to become a permanent member. It does cost a little more than your traditional gym, but you’ll also push yourself to come and will actually enjoy it. What makes it worth it for me: my child is welcomed(at no additional cost), no waiting for machines, trainers correct your form, multiple sessions a day to fit anyone’s schedule, I feel more motivated, everyone is so encouraging and welcoming, trainers help troubleshoot your diet, classes aren’t too large so it feels like you have a personal training session everyday, last and most important, 45 minutes here is a better workout than when I spend 1.5 hours at regular gym. If you’re considering trying something new, definitely come check out this gym. You will not regret it!!

Fantastic experience: I worked out here for a few months and had a great experience. The owners who are also the trainers, Jennifer and Daniel, are awesome! The equipment they have and the workouts are sure enough to burn tons of calories to lose weight and build muscle! It’s a clean facility, great workouts, awesome members and also kid friendly! I highly recommend Master Trainers!

Fantastic experience: I am so thankful for finding Master Trainers! It has truly been life changing, and I have lost 40 lbs since I have started with them. Jen & Daniel Jones make it priority to provide the best services to all members and truly care about your progress. With multiple classes a day and meal planning seminars, they make sure to set you up for success. The classes are challenging but so much fun! I have never been excited about going to the gym until I found them! Thank you Master trainers for giving me the tools, knowledge, and motivation to change my life!

Fantastic experience: I love this place!!! As a person who has joined their fare share of gyms, I can honestly say this place tops them all! I’ve been with them since February 2018 and in 9 months I have lost over 30 pounds! They have the knowledge and tools to help you reach your goals! And not only that, but the classes are enjoyable and I don’t dread going to them!!! So happy I found MTC!

Fantastic experience: Absolutely love this gym! The trainers are amazing at what they do. I am so excited to continue my fitness journey with them.

Fantastic experience: Best bootcamp in Modesto! Hands down. Fun environment, great workout, even better results!

Fantastic experience: Where do I even start . . . . . the trainers are husband and wife and make a great team . They push you to do better and better . Better than you thought you could do. Every workout is fun and challenging. Every day they explain them and make sure to show you easier ways to do them if you are having a hard time. There is a section where your kids can hang out and watch a movie or play. It's truthfully like a huge fitness family. If you have ever wanted to join a boot camp this is the one to join. You won't regret it.

Fantastic experience: Love it here!!!! Lots of fun and laughs and motivation overall.... being able to bring my son and have him in the kids cave while i workout is a huge deal breaker for me.... that was always an excuse for me and now i can be held accountable for not showing up.... no excuses.... fast, fun, and family!!!!

Fantastic experience: Dan and Jenn do a great job ensuring a focused workout and fun experience.

Fantastic experience: If your looking for a challenge and to better yourself, Master Trainers is the place for you. Jennifer and Daniel are there to help and push you towards your fitness goals. What I love is the classes are always different and make it so you want to come back for more. So thankful to have found a gym like Master Trainers that has not only kept me motivated but has helped make me a better person AND helped me feel better about myself.

Fantastic experience: Hands down the best bootcamp ever! It's challenging and hard at times but anything worth having doesn't come easy right?! The trainers are absolutely amazing!! They are very encouraging and definitely know how to make things fun! Best decision I made was joining them! If you haven't yet, please check them out, you will not regret it!

Fantastic experience: These are fantastic trainers!! Definitely worth the time and money. They have a great workout schedule, they will teach you about nutrition and healthy meals and help figure out what works best for you. Jen and Dan are not only awesome trainers, they're super nice people that are there to push you and help you become the healthy, fit and confident person you want to be.

Fantastic experience: My journey started with a message to somebody I didn't know. It was a message asking for help. I had reached my rock bottom. Worried, scared and unsure I continued to message Jennifer explaining that I had issues associated with PTSD. My message was not only heard but was met with compassion, sincerity and most importantly she helped to create a place of comfort. "Fitness will save your life." Words that have impacted my life far beyond my expectation. I was given a tour so I could visually see where I will be. I had issues with the unknown and small spaces. My first few weeks were rough. I would have to stop due to anxiety from not being able to breathe. I would sometimes feel anxious from being around others I didn't know. Jennifer gave me that space, was patient knowing I would return. I did return. Every day after I left I felt a little better. Each day more than the last. 3 weeks passed and I was no longer having anxiety. I was now pushing harder, stronger determined to be a better me. Here I am roughly 17 weeks out and I am over 20 pounds lost! The inches just keep falling off! Master Trainers started the foundation that helped create a new me. I would not be where I am now if it wasn't for Jennifer and Daniel. Private Facebook club to share the ups and downs of this journey. The countless messages of fears, feeling down and or questions. Jennifer answered every one. Messages filled with encouragement and motivation. That same attitude has rippled down to all of us. Constantly encouraging one another to reach whatever goal we may have. This is not just a place to go and work out. It's a place where family is. A place where a team is. It's a place for you.

Fantastic experience: I knew very little about fitness, health, let alone what I actually wanted in my fitness goals. I don't like to write reviews unless my experience was fantastic! This was, the trainers are experienced, know what they're doing, answered every single question and provided to me personally. At first I was scared, this skinny guy with a a slightly extended belly seeking training. The moment I shook hands with the owner all that melted away. Thanks Master Trainers of California! You guys were in constant communication, helped me feel better physically and mentally and now I am more motivated to get in shape, stay fit and eat healthier. They put the personal in personal training but with a professional touch. Thanks again!! Central Valley, Master Trainers says it all - check them out and maybe I'll see you there!
