WASHINGTON, DC—According to a Department of Labor report on job retraining, 21 percent of American women are training to be yoga instructors, marking the highest level of female interest in the flexibility-and-spirituality-expansion industry since 1971. "One particular indicator is striking: All but 32 women in New York and San Francisco are now certified yoga instructors, specializing in either hatha, bikram, or ashtanga yoga," Labor Secretary Elaine Chao said. The report notes that the rising interest in yoga instruction has caused a commensurate depletion in the ranks of massage therapists and board-certified realtors.
