I found this gym while visiting on a work trip and it is hands down the coolest if you like functional fitness. They have classes but also, 24 hour access so you can workout on your own time. They provide access to the sound system and when I was working out, nobody was there so I could listen to my music and get a good one in. Everything there from assault bikes, KB's, racks, etc. Vicki is great and made me feel super welcome. I would have bought a shirt if I remembered - wish they had one of these in Encinitas!

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!

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.

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!

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.

The owner Vicky is super accessible and friendly, and teaches great classes as well! It is a gem in the neighborhood.

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!

This is a one of a kind gym! Moved to Denver from NYC and was looking for a gym within walking distance that didn’t feel overwhelming and had a variety of classes.

Open gym hours are so flexible and really easy to access and fit with your schedule.

Endorphin is a Fantastic Fitness Studio/Gym, and a great community in which to pursue your fitness goals. The coaches/ trainers are supper friendly, enthusiastic and positive, and will encourage you to reach your goals without any pressure. Everyone is able to workout at whatever level or intensity that works for them, with no judgement.
They have multiple different types of classes, including HIIT, Strength training, Cycle, TRX row, Boxing, Yoga, Barre, etc..., at multiple times throughout the day, 7 days a week, and also have an "Open Gym" option which allows access to the workout facilities anytime with an included key fob.

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'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.

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.
