"Each 50-minute class at this weight-lifting studio tucked away on one of the quainter streets below 14th street is designed to chisel and strengthen. The classes run the gamut—there’s Legs & Butt, Chest & Biceps, Full Body, Legs & Shoulders—and the playlists are mood-boosting mashups of radio hits that make the dumbbell drills fly by. The instructors are thoughtful, patient, and, of course, enviously toned. "
