I am in a similar situation, advanced exerciser, choreographically challenged! I did buy the beg/int workouts for that reason, and I would say that if you are brand new to Cathe's choreography, they are helpful. I had already figured out the step patterns for CTX Step Intervals by the time I bought these easier workouts, so they weren't that helpful. But, I did think they would have been helpful if I had bought them before I did CTX. Cathe does take you through a couple of tricky moves (one of her around the world moves, step-face-in-over). That being said, the workouts ARE, as many have said, too easy aerobically. I haven't used them again. I am now just learning the steps for Step Blast, and I found that doing the warmup and first two combos TWICE on the first go-round and waiting to learn the third (so that I still get the equivalent of a whole workout) is a good way to learn the steps without getting too frustrated -- the third combo turns around way too much -- I was getting too dizzy trying to learn it! I'll tackle that another day.....
