I liked the small amount of hot yoga I tried, but I was put off Bikram by learning about the man and decided I didn't want any more of my money to flow in the direction of such a sociopath/megalomaniac. I wish there were more non-Bikram hot yoga classes around, particularly in my neck of the woods!
