If you fancy trying yoga—or if your doctor or therapist has recommended it as a treatment for stress—Mama Nirvana will start you at a level you can manage. Its staff know how to deal with beginners who "are worried that they'll feel foolish, that they'll feel lost in the class, that they're not flexible enough," says co-owner Ruth Anne Lundeberg. Lundeberg and her husband, co-owner Josuha Schumer, are trained not only in yoga but, on Schumer's side, in sports management and exercise science.
