A rock-climbing wall. A regulation-sized boxing ring. Manhattan’s only indoor volleyball court. Over 100 group fitness classes a week. A 75-foot pool with Hudson River river views. Saunas, steam rooms, and sundecks to spare. These are just some of the incredible fitness facilities and amenities offered by the 150,000 square-foot fitness haven that is Chelsea Piers. This is not just a gym – it’s a lifestyle and a community.
