In the year since the high-end New York chain opened a location in the Back Bay, Bostonians have been flocking to this ideal spa-gym hybrid. The sleek, inviting space holds not only the latest fitness equipment, but also studios for Pilates, cycling, and myriad yoga classes (pranavayu, vinyasa flow, anusara, and power). Inclined toward pampering? Avail yourself of the full range of massages, wraps, and facials. Afterward, the juice bar and free WiFi in the lounge help recharge body and mind.
