Step Moves has the most complex (and frustratingly difficult) choreography of all of the many (but not all) Cathe step videos that I've tried, including LIC. It does feel good to conquer Step Moves once you learn the steps. The cardiovascular challenge is only intermediate, not advanced IMHO. I've found that this video sits and collects dust on a shelf because I prefer to do the IMAXes, Intensity, and now LIC and other LIS DVDs. I thought I'd probably do Step Moves on a day when I was tired, but I don't do it often enough to remember the sequence of steps. All in all it's my only real disappointment among the Cathe purchases that I've made. I like Athletic Step in the Shock Cardio series much better than Step Moves because the choreography is not as complex but the cardiovascular challenge is greater.
