Yoga, a spiritual and ascetic discipline that has its roots in Hinduism, is practised almost everywhere by both the young and old.
According to a study done by American yoga site Yoga Journal in 2012, it is estimated that around 20.4 million people have taken up yoga in USA alone, and the number is set to increase.
