podcasts are the best! I initially started listening to them while I was at the gym or driving but recently I have discovered yoga podcasts(thanks to a fabulous friend of mine)! they are amazing- now I can do my practice at home but still enjoy the benefits of having someone guide you through your class. I also found some good classes on youtube that I listen to as well. of course, I still really enjoy the class atmosphere and the hot room so I hit up the studio about twice a week..
