I just tried Bikram Yoga aka Hot Yoga. It's madness! Non stop action for 1.5 hour. 26 postures with short intermittent rest. Freaking tiring. It's totally different form Hatha Yoga. I am given 2 more free trial sessions. One thing I know for sure is that I will not sign up for a package. The last thing I want to do is to tire myself out like that after a long day at work.
