Query: CONFUSING!

I was searching for a good cardio video and wanted to try something new. I have been doing step classes, cardio classes and have taken many dancing classes over the years. This by far is one of the most CONFUSING tapes I've ever tried to use. Yes, it is a good cardio but half the time I'm rewinding just to figure out what the heck she just did! There is not explanation of the moves just Amy calling out names that mean basically nothing to me. I usually just get so frustrated because I get lost or thrown off and by the time I've got it down she's moved on to something else. Do NOT buy this if you are not a dance/move EXPERT. Seriously, I wish I had never bought this. It is not worth the frustration and confusion. BUY SOMETHING ELSE PLEASE! SAVE YOURSELF THE MONEY!
