"Today more than a hundred types of yoga are practiced. Braver souls try power yoga, which does not pause between poses, or Bikram Yoga, pioneered by Olympic gold medal weight lifter Bikram Choudhury, which takes place in rooms heated to a minimum of 105 degree F. In the United states the most widely practiced yoga is the slow and gentle hata yoga, in t which the instructor takes students through a series of poses while helping them become aware of and change their breathing and thought patterns."
