After a few committed months of hot yoga at a studio in New York, Christina Rice had found her niche. So when the studio announced that it was offering teacher training, she signed right up.
There were 54 other women and men in the 10-week course, and not one of them looked like her. She was the lone African-American in the class.
"I did bond with some of the other students," says Rice. "But I did feel very isolated at times. There were no teachers of color. I didn't have another woman who looked like me, who understood my struggles, my insecurities.
