I can’t say enough great things about this gym! As a personal trainer, I need space that’s not only clean and well-equipped but also welcoming for my clients - and Core Fitness checks every box. The equipment is top-notch and always maintained, there’s plenty of space for functional training, and the atmosphere is motivating without being intimidating. The owners clearly care about creating an environment where both trainers and clients can succeed. My clients love coming here, and I love being able to deliver high-quality sessions in a professional, supportive setting. Truly one of the best independent gyms around!

Core Fitness NYC is one of the best gyms for independent trainers or anyone looking for a space on the UES! Michael and Denise are both incredibly kind and high energy, which is evident in the space they have built. Highly recommend!

I've been training in Manhattan for 15 years and can say without a doubt that Core Fitness is by far my favorite Independent Personal Training Gym in NYC. Owners Mike and Denise are always looking for ways to improve the gym and keep it the best fitness studio on the Upper East Side. Personally training clients here for 13 years in a prime location, with 24/7 access and fair rates, has me looking to continue my business here for another 30 years! Trainers, you will not regret bringing your clients here!

Love every minute I get to train with Denise! I had 7 weeks to cram in marathon training and Denise got me there! I still train with core-fitness after my marathon because she Curated workouts specific to my needs and the location is convenient in UES. Easy to get to after school drop off in the am. Denise is a knowledgeable athlete herself, she knows all the ups and downs of training and was with me every minute of my training and during the race. Totally dedicated team at a top quality gym!

I am OBSESSED with Core fitness. my husband and I are workout junkies and no one has challenged us more. each workout is unique and challenging and kicks our butts but in a thoughtful and safe way. I am certain that each session is tailored to my body and thoughtful. Denise understands my body, knows how to work around injuries and even reaches out at nights to make sure I am doing the necessary recovery work to stay healthy. I cannot recommend them enough!!!

I found this gym through the Carol.io website since I wanted to try the bike. I was only in town for the week and the Owner was very friendly and helpful. The gym was full with top notch equipment and trainers ready to help.

All about strength! No frills gym that has everything you need for strength & conditioning. One of the few places that allows outside trainers to bring clients. Have every piece of equipment imaginable - both old school and the latest. Owner Michael M. is welcoming and provides a nice atmosphere.

Great place for personal training. You will find a trainer with expertise in just about anything here. Work out at the gym or take your training into central park. You will love it. Mike the owner is a real charmer, and his wife Denise as well.

This is a fitness buff's fitness place, a boutique facility for those who are serious about their training, with the best equipment and latest technology. The owner, Michael, is a real fitness engineer—he designed a dynamic program focused on my goals and mindful of my injuries, and delivered results that have exceeded my expectations. My husband calls him a genius.

It's a terrific workout space that never feels crowded, provides towels & water, and has great trainers to boot!
