Redefine Fitness is a medical fitness company in Mount Sinai, NY — the bridge between where medicine drops you off and training on your own. Not a gym: private, appointment-only, one-on-one. Every program starts with a Biometric Analysis & Movement Screening — InBody scan, strength and movement baseline, and health-history review — so your plan is built from data, not guesswork. Nutrition care from our Registered Dietitian. Specialists educated through the system behind New York State’s only DOL-approved fitness apprenticeship. Done-with-you training for people 40+ who want to train smart, build strength, and add healthy years. Infrared sauna on site. Not the cheapest option, and not trying to be. We are medical fitness.
