Bikram Yoga is a series of 26 hatha yoga postures or asanas (see also the 26 'Live" Posture Photos) done in a specific order over 90 minutes in a room heated to just above body temperature. The series was brought to the US over 30 years ago by Bikram Choudhury, who learned the yoga from his guru Bishnu Gnosh (brother of the famous Paramahansa Yogananda).
