HIIT Classes

Ages 18+

HIIT (High-Intensity Interval Training) workouts combine short bursts of intense exercise with periods of rest or lower-intensity exercise to torch calories, burn fat, and build muscle effectively. High-intensity group fitness classes are temporarily suspended. We’ll bring them back as soon as we’re permitted by the city.
