Endorphin City Park

Fantastic experience: We showed up to the wrong location and class and were forced into it - door locked and everything...but Scott made being terrified worth it

Fantastic experience: I love this place. Shreads is the best strength group fitness class I’ve found in Denver. I’m a PT so I can be picky about instruction but every instructor I’ve had knows their stuff, comes up with a great balanced workout, gives good cues, gives good modifications, and brings the hype and motivation. Also they are on ClassPass!

Fantastic experience: Instruction is always spot on, everyone is so encouraging and I love the whole community feel.

Fantastic experience: Difficult class, but great energy in the room!

Fantastic experience: I felt welcomed and comfortable there. Instructor was accepting of my limitations which was very helpful. Participants were friendly. I am happy to be a participant at Endorphin. What a great place! Thank you!

Fantastic experience: I was in denver temporarily and went to this gym twice. Nick is super friendly and helpful with correcting form. Also there is a cute dog here!

Fantastic experience: Great gym: stocked with every possible equipment for HIIT, weightlifting, boxing, and mat-based classes. I've taken classes with 4 different teachers so far, and they're all enthusiastic and encouraging. The bathrooms have plenty of space for changing and are equipped with showers and essential hygiene products. I especially love the flexibility of having 24/7 access with my membership and key fob.

Fantastic experience: I moved to Denver in August and was at first nervous to join a new gym, especially after being limited by an injury. The teachers and community are super welcoming, helpful, and accommodating all the time. I have noticed myself getting stronger and more confident! Great spot.

Fantastic experience: Christa’s barre class is one you’ll never forget. A full hour discovering muscles you never knew you had. What a great workout!

Fantastic experience: Updating for 2025: This is still an A+ spot! Sam and Vicky and Allie are wonderful coaches and the fellow athletes at the gym are very nice and welcoming. HIIT, Strength, Yoga, Barre, Boxing. Lots of variety here, and can use the other two locations in town on a membership; very useful when running errands in a different part of town or when schedules don't align perfectly. This place is terrific for ClassPass. Shreds is a great burner every time!

Fantastic experience: Former class pass user now full-time member, this gym makes it easy to become obsessed with exercise and feeling good. Some of my favorite classes are shreds with Allie and Sam, hot ride cycle with Logan and yoga with Alicia. The people who attend are super nice and the coaches are so inclusive - highly recommend!!

Fantastic experience: Great Denver gym, I've been going for about 2 years now and can't recommend it more highly. It is always exceptionally clean, and has a great open gym area. Awesome classes of a wide variety, I primarily go to Sam, Emily and Logan's classes and they are all challenging yet fun in different ways. The owner Vicky is super accessible and friendly, and teaches great classes as well! It is a gem in the neighborhood.

Fantastic experience: Love this community space. I’ve taken my first class, and Sam was great and very welcoming as an instructor for a newcomer, the class was fun and difficult, and made great use of the space with great programming. Big fan.

Fantastic experience: Came here to try a class whilst I was passing through Denver Was hoping for something similar to my gym class in the UK, and got exactly that but better. Plus it felt very welcoming. Being paired up for exercises means you don't feel isolated on your first visit when you don't know anyone, and Sam the instructor is super friendly and knows how to push you the right amount Wish this was my local!

Fantastic experience: AMAZING GYM!!!! I love this gym so much. I’m a physician with a chaotic schedule and the wide span in class times from early morning to afternoon to late night allows me to go to the gym 5-6 days a week consistently. I can take a wide variety of classes all at one gym — weight lifting, cycling, yoga. Coaches are extremely knowledgable and friendly! I am so grateful to have found Endorphin City Park.

Fantastic experience: Fantastic locally owned/operated gym. I've been attending all sorts of classes here for years (yoga, spin, hit, etc) and the instructors are all very welcoming to newcomers, and push the regulars to encourage them to improve!

Fantastic experience: This gym has an incredible community. Super awesome vibes. The instructors are fantastic! They understand body mechanics and can adapt workouts for all fitness levels. If you need a challenging class that targets strength and cardio, take Shreds! I explored so many gyms in Denver but Endorphin is by far the best!!

Fantastic experience: I've been to a number of gyms in my life and Endorphin City Park is by far one of the best! From friendly knowledgable instructors, to positive supportive gym mates in a judgement-free zone where you can get a great workout and have fun doing so! I love the variety of classes, packages, and schedules they offer that I can customize according to my goals, budget, and needs. Never hurts to try one of their free intro classes and signing up for their new member unlimited month package (the price is a steal!) — that's how I started and been loving it ever since.

Fantastic experience: Convenient and cool people. Not bougie! Also very affordable! Love the spin class and options for open gym!

Fantastic experience: I have been a member for 13 years and highly encourage people to check out Endo's awesome fitness classes. Nothing beats having an instructor motivate you in person. Endorphin rocks!

Fantastic experience: Lovely gym! All of the classes are great, the instructors are so nice and take time to make sure you’re grasping all of the concepts. And the community there is very welcoming. 10/10

Fantastic experience: Brandon H makes weight lifting fun, approachable, & effective! I was a total beginner when I started but have increased my strength at least 30% in the past 18 months.

Fantastic experience: Love the classes here!! Every class is different! challenging and never leave without feeling like I accomplished a great workout!

Fantastic experience: There is a diverse set of options in terms of group exercise classes. The instructors are knowledgeable and are happy to correct your form if needed. My favorites were barre and yoga - always pushed me to the next level.

Fantastic experience: I started going to Endorphin in 2018 and the only reason I am leaving is because I am moving out of the state. This gym brings sweats, smiles and jams to every class. I’ve done Warriors (fan favorite), cycle / row, yoga, barre, kinesis, shreds, strength & conditioning, and dirty 30 (there are probably more I’m forgetting) and I’ve enjoyed every single one of them. I don’t know how they do it but this gym is just full of phenomenal instructors. It is also a wonderful community to be a part of. Everyone is so kind, welcoming,and encouraging in class. There was never a day that I regretted going. To be honest, there are probably more days that I regret not going! I’m sad to be leaving Colorado, but I’m probably the most sad that I won’t be able to find a gym that I love as much as Endorphin somewhere else.

Fantastic experience: Everyone is wonderful here! The instructors are so knowledgeable, and even though I'm a solo exercise person, and gravitate toward heavy lifting, they always take time to help me with more nuanced exercises. Highly recommended!

Fantastic experience: I love this gym! The community is great, awesome teachers with a variety of classes, times and locations. Definitely get the feeling they are happy to see you! Been a member for a couple years and I love it!

Fantastic experience: I love Endorphin! There’s a variety of classes, instructors, and locations which makes it easy to find something that fits in my schedule. All the instructors are super welcoming and the community is down to earth - it makes trying all the classes and new types of workouts less intimidating :) You’ll find everything from yoga, HIIT, boxing, cycle, strength, barre…it constantly challenges me!

Fantastic experience: Love the Endorphin community! All the instructors are so nice and welcoming! Each class will push you. Don’t come here if you want an easy workout! You will see results and have fun while doing it! This location is always clean. Love the variety of equipment.

Fantastic experience: I absolutely love this studio! Tuesday virtual yoga classes with Megan are one of the highlights of my week. :)

Fantastic experience: My favorite gym in Denver. Awesome group classes!

Fantastic experience: I did my first-ever spin class. The instructor Emily was very helpful in gettingmy cycle set up and making sure I knew what to do before class started. about halfway through class she saw I was struggling and checked on me. If the class want so great, I probably could have finished it. Instead it showed me that I clearly need more regular exercise, and I will definitely come back to endorphin for more spin classes

Fantastic experience: Took a power vinyasa class with Aretha this morning and loved it. I've had a shoulder injury for the past year and tried everything. Lacrosse ball, hanging, resistance, nothing worked. I did not realize until I left Aretha's class that my shoulder felt better than it had in years. I don't know what voodoo she did but I'm not going to question it.

Fantastic experience: Erin’s Vin/Yin classes on Saturday mornings are my favorite yoga classes. If you’re searching for the perfect combination of vinyasa flow and regenerative postures this class will surely satisfy your needs.

Fantastic experience: I have been a member at Endorphin for 6 months and love going to this gym because the classes never get old! Today I tried a Yin Yoga class with Erin Wimert at the City Park location and it was the most relaxing hour! I left so rejuvenated, love going here.

Fantastic experience: Love this place! The classes, instructors and community are terrific. Especially love Andrew for Kinesis, John for Yoga Sculpt and Liz and Amanda for Yoga. Great options for all fitness levels and amazing yoga and barre options. Highly recommend!

Fantastic experience: I’ve been a member of Endorphin about 5 months now and I highly recommend it. I primarily go to Barre/Yoga classes at the City Park and Park Hill locations. I’m always impressed by the quality of the instructors. The studios are clean, everyone is welcoming, and you’re guaranteed to get a good workout in!

Fantastic experience: Endorphin has a variety of time and class options. The instructors are awesome, knowledgeable and friendly!

Fantastic experience: Vin/Yin class was great! Instructor was helpful, genuine, and very soothing to be guided by.

Fantastic experience: Meg is amazing! Great class! She kept it flowing.

Fantastic experience: Stopped in for a quick work out while in Denver for work. Serious gym without being pretentious. Young man working the desk was super friendly and helpful! I just bought a drop in yoga class but they let me work out while I was waiting for class to start. Plus towels and shower after class were a huge help! If I was a member, I would love for them to have a second stair climber since it’s a popular piece of equipment. But no complaints.

Fantastic experience: I take the all levels Vinyasa and I love it. I'm a beginner and the pace and direction are solid and challenging. I'm always sore.

Fantastic experience: I love this gym! Small, great community, tough classes, really nice and helpful staff! They worked with me when I first moved here 2 months ago and again during an injury to ensure I was getting the most out of my membership, Would highly recommend to anyone looking for a mix of amazing classes from yoga to barre, cycling to HIIT workouts, I've tried them all and each instructor brings something unique while kicking your ass, I love Endorphin!

Fantastic experience: I love Endorphin! Best instructors, good energy, great location! Been a member since they first opened!!!

Positive experience: It's a small gym, but I always go to the yoga studio part of it. The restorative yoga class is my favorite and I go every week because I feel amazing after leaving. My only complaint is the size is small, and you also hear all the traffic from Colfax while the room is fairly cold when it's cold outside.

Fantastic experience: This is a great facility with friendly staff and teachers!

Fantastic experience: Bree Murphy’s Restorative Yoga class is my favorite way to keep my body limber, my mind calm and my spirit centered.

Positive experience: Fantastic workout and very challenging. Leader was encouraging. Would like to have music going while working out.

Fantastic experience: Great Organization of a really tough workout! The coaches are very helpful and extremely motivating!

Fantastic experience: workouts in the morning really get the day going on the right foot. jordan andrew and bree were great with me as a total beginner, keeping an eye on form and encouraging me to keep going.

Positive experience: I really like the variety of Endorphins! The instructors and incredibly friendly and helpful. Each instructor wants to know your name and check in with you after each class.You feel welcomed and included compared to other gyms I have been to where you feel like a monthly payment and no body cares of your progress. I really enjoy the Kinesis class. Very challenging but fun circuit training. Personal trainer Courtney is amazing! Very encouraging, supportive and down to earth! Overall, very happy with Endorphins!

Positive experience: I did a yoga and kinesis class. I found both challenging and very worthwhile. I like feeling like a did something after a class. The instructors were enthusiastic.

Fantastic experience: I have never found a gym that has great HIIT, yoga, and cycling classes - until Endorphin! The trainers are great and the classes are fun. I am NOT a morning person and I've been waking up for 5:30am classes!

Fantastic experience: Great teachers and classes for beginners.

Positive experience: Yoga was welcoming and fun!

Fantastic experience: Favorite gym I've ever belonged to. The instructors are great and I love the variety of classes offered.

Fantastic experience: Fantastic instructors, nice space, good community. Only critique would be sometimes the music from next door can be distracting.... Which I suppose is a good test of concentration!

Fantastic experience: Endorphin is the best gym! Great class variety, innovative, friendly staff and instructors, and always clean!
