There are yoga studios and yoga styles to suit almost any practitioner -- but not just any budget: A serious yogi is looking at dropping $120 a month for a class card at most studios. At the Oxford Club, $50 a month ($600 a year) buys yoga seven days a week, plus access to the work-out facilities -- weights, free weights, treadmills, bikes -- and locker rooms stocked with Aveda products. But just because the price is low doesn't mean the studio is some dank, second-rate space. It's light, airy and big enough to spread out in. To sweeten the deal, membership includes twelve free-valet vouchers and discounts at McCormick's restaurant and on spa services and nights in the Oxford Hotel. Om.
