Core Rhythms

Well, I broke down last month and bought Core Rhythms. I've got to say if anyone is interested in it, save your money! It is very hard to follow and I don't feel like I'm getting a workout at all.. in fact, I don't even break a sweat. I break more of a sweat doing the biggest loser workout (which is 3x's lower the price that I paid for Core Rhythms)I'm really disappointed in it.  Just had to vent lol..sorry!
