I've only done this workout via fit-tv, and at first it was tough as I did not have much previous experience with Cathe's step. I also leave out turns and pivots, and when I'm stumped, I will watch Cathe and count her foot movements. If a move has 4 beats to it, as I'm doing it, I will count 1,2,3,4 and I usually land on the correct foot.
For some reason I have the hardest time following her when she is in front of the step.
Now that I have down the fit-tv version, I really enjoy doing it and hope to order the dvd soon. The premixes look great.
Hope the counting thing will help.
