Personally, I love this step workout. It has a lot of new steps, or did for the time when it was released. It starts off deceptively easy and low intensity and rapidly builds. You might think it is going to b very complex from the choreography of the first few minutes, but not so. It soon graduates up to power moves and the music is good. I cannot remember which upper body muscle group is targeted after the step workout. Since this tape was only one of 6 meant to get you through the week, with 5 cardio options, total upper body muscle conditioning and a lower body endurance weight training day, it is only one part of a multi-day program. But, worth having for the cardio workout. See if you can pick up some of the others in the CTX series, although if I remember correctly, All Step was given away with a step, both were marketed together, so there could be many copies of All Step floating around odd places. Check ebay for the others in the series, if you are interested.
