I did Bikram yoga for years - the hot sweaty kind - and loved it. The studio changed their class schedule and I'm unable to attend due to work (yeah, I know just where are my priorities ). Hatha is very peaceful for me; Ashtanga is more athletic. I have never disliked any type of yoga I've tried. At all classes I've attended the instructors are very attentive to the student's abilities and flexibility.

I am thinking of going to this weekend's Yoga for Peace event here in San Francisco's Golden Gate Park. Three hours of sun salutations - it sounds intense, but you go at your own pace and stop when you need to. They're doing it all over the U.S. in memory of those who died on 9/11.
