Writing in the New York Times, Gretchen Reynolds answers the question “Does Yoga Build Strength?” The short answer is no, but wait, there’s more. Reynolds points us to a 2012 study of premenopausal women who were randomly assigned to twice-weekly 60-minute Ashtanga yoga sessions or to a control group. When, after eight weeks, the overall strength of both groups was evaluated, the yoga group was found to have stronger legs–stronger both than when they started and stronger than the control group. What about other muscle groups? Not so much. OK, not at all. And no, Ashtanga yoga did nothing for cardiovascular fitness.
