I have never done any aerobics workout other than the stair stepper at the gym. I have been wanting to try one of Cathe's aerobic tapes because you all make them sound so good. I went to K-mart and was going to get a more expensive stepper when I noticed the less expensive one comes with a Cathe tape. So I figured I'll get the less expensive stepper which is smaller (I don't have alot of room to work with) and I get a bonus with a Cathe tape too! I think the tape is called All Step. I can't wait to try it tonight!
