I am an avid exerciser (especially cardio/arobics), so when i had read several reviews not recommending this tape, i decided to use my amazon.com gift certificate to buy Keli Robert's Total Body Circuit Training Workout and her Abs and More tape. Yada-yada-yada, I selected the wrong combonation of tapes and got the Ultimate Step Workout tape and the Circuit Traning Workout tape. This morning, I just did the Ultimate step tape and I LOVED IT! The steps definitely need improvement on my part (i did it without first watching it because as a dancer I figured i could catch on, but i was a little less than right!) but i can really see myself doing this tape at least once a week (i have to rotate it with her other amazing workouts, Cherfitness 1, and the Circuit Training tape). Some people were concerned that this wasn't great for beginners, but if you watch it first and do only what you can and pay attention to the ones modifying it, beginners can do it too! Anyone can benifit from this tape, especially from the abs work, it's a real workout, but i still can't wait to buy the Abs and More tape!
