Emily and I have been attending some Bikram Yoga classes in Westboro. This is an intensive yoga in a highly heated and humid room. Every class is 1.5 hours long. I drink a large bottle of water and still loose a few pounds of water. Best sweating I've had since I ran my marathon. This isn't what I expected from yoga. Yoga I've done in the past focused on stretching. Bikram Yoga certainly has stretching, but it also strengths your muscles and bones. Fun fun fun! Peace!
