When Robin Brown decided to open Clay, a new workout haven in New York City, her aim was to create a space that would emphasize far more than a firm derriere. "Clay is a place to make over your entire lifestyle," Brown says. The gym offers cooking seminars, nutritional counseling, and an organic café. Classes range from hard-core kickboxing and boot camp to yoga, swing dancing, Pilates and meditation. And then there are the post-workout perks: a fireside sitting area drenched in sunlight from the overhead skylight, a rooftop lounge, and plans to open a sports spa downstairs next spring. Race you to the locker room. 212-206-9200; www.insideclay.com.
