Definitions American College of Sports Medicine ACSM certified personal trainers have created custom work outs for New Yorkers since 1983. Expert instructors guide you one on one in training, excercise, and total fitness programs to get results. Our 3 Manhattan private gyms offer the best facilities in NYC.

Our unwavering standards make becoming a DEFINITIONS personal trainer a long process. And like our clientele, there’s not a lot of turnover among our trainers. We conduct interviews on a quarterly basis, eventually winnowing down the pool to two or three exceptional candidates. Regardless of prior experience and education, each new personal trainer must undergo a minimum of 160 hours of DEFINITIONS training, and all are certified through the American College of Sports Medicine. The results of this training program are obvious to DEFINITIONS clients: professional personal trainers who are charming, but firm; focused, but accessible; proficient, but eager to learn more.
