Yoga dates back to 2500 B.C. as an ancient Indian practice (Tran, Holly, Lashbrook, & Amsterdam, 2001). Yoga focuses on the union of the mind and body. The key concepts underlying the practice of yoga include meditation, breathing, and focusing on centering the body's energy (La Forge, 2005). In the 1990's, the popularity of yoga grew rapidly throughout the United States and Europe as a mind-body exercise (La Forge, 2005).
