I took a semester of yoga at the local community college. It was very relaxing and enjoyable. There was one time we had a substitute teacher and she had us sit & listen to whale noises and stuff, so that was a bit much for me but I really liked the way our regular teacher ran the show. I felt like I got my money's worth, and now that I know the proper way to do all the poses, it's easy for me to do it at home on my own. Although,
savasana just isn't the same without some hypnotic monotone voice telling you to relaaaaax... right as I would doze off some older lady in my class would start snoring and wake me up.
