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!
