I'm reviving this thread because I went to my very first Bikram Hot Yoga class yesterday! I've done Vinyasa yoga & loved it. I haven't been to any yoga class in almost 6 months.
Can I just say - WHOA! That class was extremely challenging. I think the largest challenge was just staying in a 110 degree room for 90 minutes. Also, once you start sweating, its hard to maintain any of the poses that require skin to skin contact - like eagle pose & tree pose - I kept slipping. Is there some secret here??
There we a few times I got very light headed/dizzy & had to recoup in shavasana. And absorbing all of the verbal info constantly coming at me was different. Apparently that is to be expected for newbies. Overall, it was very challenging, cleansing, balancing. I'm going back for my 2nd class in about an hour! I figure doing something that is hard, but good for me, is better than some of the things I'm dealing with that are hard & not good for me.
