I have found a crazy fun exercise program (although I find ways to NOT do it, I LOVE it when I do.) Yoga Booty Ballet...yes it combines, Yoga, Silly dancing, and some Ballet and balance moves. It's a DVD collection and used to be on those late night infomercials - as a habitual insomniac, I've seen em' all, and this was the only one that really caught my eye.
Fun, silly, and great for all levels. With sessions like "Cardio Cabaret" & "Bollywood", you can't NOT enjoy doing the workout even if you can't keep up.
You can find them at your local library or on Ebay!
