New York Fit Body Boot Camp, Mamaroneck

Although New York Fit Body Boot Camp was founded by award-winning bodybuilder Butch Nieves, its workouts focus less on bulking up than on slimming down. Featured in The New York Times and The Wall Street Journal, the workout regimen melts fat efficiently with a blend of four fitness essentials—cardio, resistance training, body-weight core training, and ab workouts. Exercisers build toned muscle during the fast-paced sessions, ramping up metabolism in an indoor studio outfitted with foam flooring that cushions joints. Certified personal trainers lead each class, motivating clients with supportive words, rather than by barking military-style orders or threatening to replace water bottles with steaming teapots.
