ENCINITAS, CALIFORNIA The practice of yoga began in India more than 2,500 years ago. It was introduced to the West about a century ago, and has become increasingly popular. For some it is an exercise, for others it is also a spiritual practice.

She loved it so much that this year, at the age of 12, she decided to teach it.

"Im the youngest certified female yoga instructor in the U.S.," she said.

DeVoe teaches yoga every Tuesday. Her entire family, including twin brother Fisher, try to attend her classes when there is room.

Ive been to every one except one because I wasnt here. I think its awesome [be]cause just like...a kid teaching yoga like... by kids for kids kind of thing," she said. "I think its [awesome].
