I signed up for Bikhram Hot Yoga last week after a friend referred me to this studio. I was skeptical of Hot Yoga to begin with becuase I thought it would be stinky in the hot studio. But I was reassured it doesn't smell and that it's an awesome workout. So i tried it out and signed up for 4 months unlimited classes. So far I'm REALLY enjoying the classes! The instructors have their different styles (how hot to keep the studio, how long to hold the poses, how much they explain what the poses are to help achieve, etc) but they are all very encouraging and help meet you at your level and then try to push you beyond to get the maximum benefits of the workout. There are first time student discounts so it's an option to try if you just want to try it for a week.
One less star from 5 because they don't have lockers so there's really no security for your belongings. They do however, lock the studio once class starts so no one can get in.
