This is such a fun way to experience the traditional Hot Yoga class. It's only 60 minutes long, however you get 2 sets of each posture just like the Hot 90 class! Music is playing in the background, and the instructor gives only minimual verbal cues. Because of the minimal verbal instruction, it's recommended that beginners have some expereince first with the Hot 90 class so they know what to expect in the Music class. Room is heated.
