I go here for the Monday evening classes. The teacher was late for one of the classes. So, they refunded us for that class and gave us a free class. I would totally recommend a great place for HIIT classes.

I left Crunch for this gym and I’m so glad I did. Great equipment, clean, great staff. I’ve been a gym person all my life and as such, pretty picky, so please believe me when I say it’s a great place to workout.

Best gym. Roomy and not overcrowded, unlike corporate gyms. You can bring your own trainer, which was the original reason I joined. Staff is personable and helpful and other members and trainers are super considerate.

Kojo is the best! I've been going to his class for a few months now and each one is different. He comes up with a new routine every week so you never get used to the same exercises. He's super encouraging and awesome to work with. I really look forward to his class every week and always find it to be a new challenge! Highly recommend for anyone looking for a great new, HIIT/strength training class.

O2 fitness has such a great vibe. It's super clean and the classes they offer are so intense. Some of the hardest workouts I've done. I take their classes through class pass and the intensity of the workout vs. the cost of the credits is by far the best value for what class pass offers. Jame's morning class is so, so great!

Kojo was a phenomenal instructor, motivated you just enough but wasn’t annoying about it. His workout definitely kicked my butt. The facility is super nice. If I lived in the city I’d consider getting one of their many deals for a membership.

DEFINITELY exceeded my expectations. The HIIT class here through ClassPass kicked my butt and I loved the instructor Kojo. I gotta admit it was probably the same if not better than a Fhitting Room class (the same structure). Hidden gem on the UES. Beautiful facilities and the fanciest TechnoGym machines.

Absolutely love this place. Equipment/space is clean, Equipment is top of the line- tecno gym/ rogue etc. The front desk is always so welcoming and the price is affordable. I actually train my clients out of this gym and the environment is super welcoming vs. competitive which i've dealt with in the past. All the trainers create an enjoyable space for other trainers and their clients. Whether you are a personal trainer looking for a space to train your clients or someone who is looking for a welcoming/inclusive space to work out in on your own o2 is your space.

My new favorite gym in the UES! The place is beautiful, the equipment is top-notch, they have a back room for weights and squats and a separate room for various classes! Their fitness classes are my favorite and they have the best trainers! My fav is James Brewer- he is fantastic. I highly recommend this gym.

Great atmosphere, the staff is very pleasant and professional. You will find all the equipment needed for your workout and then some. Very clean and friendly environment. Also convenient location. Please check out their extra curriculum classes, they are designed to meet different goals.
Everyone who comes to O2 is serious about their purpose.. and did I say encouraging?
All trainers are great here, but MO is the man💪 Thanks for pushing me beyond my comfort zone.

Here’s a shoutout for “O2 Fit Nation,” a recently opened wellness center and gym at 201 East 71st St off Third Avenue. “O2” is a state-of-the-art workout facility with the latest Technogym fitness equipment. The gym has ample lockers, clean and modern changing rooms and bathrooms and sanitizing stations throughout. Nilson de Souza, the owner, is a professional trainer with a graduate degree in exercise physiology and many years experience in the field. I know Nilson since 2008; he is an excellent trainer. You can’t do better than “O2” if you’re looking for an all around workout facility.

The gym is amazing it’s been open for a few months. I know the owner Nilson professionally and personally. He put a lot of time and effort into making this gym One of a kind and the best one in New York City (well that’s my opinion lol) everything is brand new. the people that work there are very friendly and always do their best to accommodate everyone. Whether you workout with a personal trainer or you workout on your own O2 Nation is the gym you want to workout in. I highly recommend you go and get a membership ASAP🥰🥰💪
