Since 2001, the popularity of yoga in the USA has expanded. The number of people who practiced some form of yoga has grown from 4 million (in 2001) to 20 million (in 2011). It has drawn support from world leaders, “Yoga has become a universal language of spiritual exercise in the United States, crossing many lines of religion and cultures,… Every day, millions of people practice yoga to improve their health and overall well-being. That’s why we’re encouraging everyone to take part in PALA (Presidential Active Lifestyle Award), so show your support for yoga and answer the challenge”. The American College of Sports Medicine supports the integration of yoga into the exercise regimens of healthy individuals as long as properly-trained professionals deliver instruction. The College cites yoga’s promotion of “profound mental, physical and spiritual awareness” and its benefits as a form of stretching, and as an enhancer of breath control and of core strength.
