So says outspoken yoga master Mark Whitwell, who's been delivering some chakra shock waves to American yogis in recent years by claiming that treating yoga like just another fitness class—90 minutes, three times a week—means we're losing out on the stress-reduction benefits that drew us to the mat in the first place. Author of Yoga of Heart (Lantern Books) and a former student of legendary yogi T.K.V. Desikachar, Whitwell—who now practices in L.A.—believes that 20 minutes of daily yoga at home alone is the essential foundation of any practice. He argues that proper breathing while moving at your own speed is vital to relaxing yoga—and nearly impossible in the forced pace of a class. "When you establish a daily practice, it becomes healing to the entire system," says Whitwell. "You're able to digest life easily." Whitwell suggests completing nine sun salutations (illustrated below) each morning, using breath to initiate the basic movements. Breathe in and out deeply through your nose, emitting audible sighs from the back of the throat on all inhales and exhales, and concentrate on flowing through the posture. Oh, yeah—and expect to sweat.
