Cornerstone Gym




Our Fitness family is made up of a diverse group coming from a wide range of disciplines. We are a hidden treasure in Chelsea, NYC and a second home to some of the City’s elite athletes, martial artists, MMA fighters, Olympians, dancers, models, corporate executives, and entrepreneurs—and those who are looking to push their boundaries.
Our coveted fitness classes comprise the second arm of Cornerstone. These are tailored around our fitness concept of the micro-progression principle: In order to reach higher levels of performance, we need to incrementally challenge our muscle systems. We are able to break through fitness thresholds by cross-training and addressing our weaknesses in a way that enhances physical condition, not breaks it down.

Cornerstone offers three foundation classes that target specific components of fitness and wellness through a combination of building power, strength, agility, flexibility, and endurance.
During select off-peak hours throughout the week, we transform our facility into a spacious, fully equipped fitness class studio.




War & Peace

As the name implies, our War and Peace class is an amalgamation of High Intensity Interval Training (HIIT) and slow twitch muscle training. War & Peace helps clients tap into the raw, aggressive, high energy components of their nature while challenging your ability to focus, connect with your muscles and breath correctly. Get the group fitness setting without the crowds. Our class is capped at 8 people to ensure you receive proper instructions and attention!
