I started the beginner's rotation but did not see it through for 90 days. Basic step and low impact step were awesome for helping me learn the step moves. I also found I was not really a beginner in the weight department. I ended up mixing things up a bit, adding other cardio as I advanced beyond the step workouts and using other weight workouts I found more challenging, until I really wasn't following the rotation at all. I have found since then that a general framework of a rotation (step cardio/upper body one day, kickbox cardio/lower body, longer cardio/abs, etc.) works better for me because I have enough Cathe videos and others that I can pick one I'm in the mood for that day that fits the bill.
This is not really an opinion of the actual rotation, just that it wasn't right for me for a number of reasons. You have to find something that is good for you and work it!
