Core fitness offers an exceptional environment for working with my patients—it's clean, well-equipped, and never overcrowded. The owner Mike Marguilies is professional and always ready to assist, making each session smooth and stress-free. I appreciate the quiet, focused atmosphere that allows for individualized care and effective progress. The equipment is top-notch and well-maintained, supporting a wide range of therapeutic and fitness goals. It’s a fantastic space that truly enhances the quality of care I can provide. I have no issue in recommending this facility!

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!
