From the person putting on gym shorts for the very first time to the gym rats who eat, sleep, and breathe dumbbells, exercisers of all backgrounds build muscle and stamina during one-on-one personal training and group fitness settings at Long Island Fitness & Wellness. The fleet of experienced instructors tailors their personal training sessions to suit the needs and goals of guests, keeping cardio and strength training challenging but always interesting. Their group fitness classes do the same. For instance, Hardbody Boot Camp uses nonstop interval training with minimal equipment, while Bangin’ Booty 101 classes—named for the first course offered at Harvard University in 1636—target specific muscle groups with free weights and body resistance. The instructors lead their sessions within a cavernous gym that sports a full-wall abstract mural.
