Go on an underwater bike ride
Don’t be fooled by the one-piece suits or the pool, AQUA is far from your standard water aerobics class. Tucked into a Tribecca storefront, the 4,000 square-foot sanctuary is filled with flickering candles, aromatherapy products, and a stunning 84-degree saltwater pool filled with exercise bikes. It’s a three-in-one exercise class, too: As you spin your way to a full-body workout, the friction on your skin from the water acts as a massage, while being buoyant helps the body recover, heal, and strengthen deep muscles. Even though the 45-minute class gets intense (water is 800 times denser than air!), the spa-like atmosphere of AQUA will balance you out. There are also daily stretching, meditating, and toning classes to take advantage of after your workout.
Cost: $35 for the first class, then $42 for drop-ins
