Fitness Center at The Knick

The Saints & Sinners Fitness Center at The Knickerbocker combines cutting-edge equipment, luxurious services, and a world-class virtual experience to motivate you every day. Named after artist Molly Crabapple’s Saints & Sinners mural—an extraordinary work of art that depicts the legendary figures who made history at the hotel during New York’s Gilded Age (including F. Scott Fitzgerald and John D. Rockefeller), the fitness complex is comprised of two distinct facilities. The spacious and serene Saints Studio is dedicated to yoga, mat Pilates, and other low-impact modalities. The Sinners Studio features machines for cardiovascular training and heavier lifting, including a state-of-the-art stretch cage and boxing system, and was outfitted in collaboration with NBA All-Star Larry Johnson—a former New York Knicks’ power forward.

Stay fit and feel your best during your stay with fitness classes led by expert personal trainers. Aaptiv gives you thousands of audio-guided workouts for treadmill, cardio machines, running, strength training, yoga, meditation and more — all set to inspiring music by today’s top artists. It’s like having a personal trainer whenever and wherever you want one – all for free while you’re in residence.
