Today I am obviously not doing too much in the way of actual work...I found this video of a news story that was done in Chicago on Bikram (hot) yoga. I think it represents what one can expect if you go to a class.
Where I go we dont have wood floors though. Berber carpet...I would think a wood floor would be dumb but thats just me. Another reason I like going to a 4:30 class rather than 6:15 class is because its less crowded (as the one here appears to be).
