Get this DVD for Step Blast alone.  A classic Cathe step workout.
I must be in a total minority because I dislike SJP.  It is "bitty".  She does a little bit of step, but each routine is real short and she throws them all away so it feels like you are learning a routine for no reason at all.  Then she moves into hi/lo and one of them is a low impact cardio session, as if she can't make up her mind, is this high or low?  With endurance weight work thrown in.  Well, I don't favour upper body endurance workout at all, and so I cannot count doing SJP as  a day's weight training.
