Bikram Yoga is an amazine workout of 26 postures in a heated room of 105 degrees. After 90 minutes, I feel like I've worked every inch of my body and have had a massage. My back is so much better and I find that I eat better, too. Sweating and working out for 90 minutes makes you think twice about what you put into your body.
