In my book, SJP is harder but C&W is a little more fun. I like to do SJP like a Body Max, do all the cardio first, then do the weight training. That's only because I really like hi/lo and don't like to break it up with the weight circuit. Sometimes I just do the cardio only premix. I did C&W this morning, though, and I really enjoy the workout as is. The choreography is good which makes it very enjoyable. Both workouts have great ab routines. When I was getting back in shape after having my baby a couple of years ago, I did the abs in SJP a lot and credit it with helping me get my core back in shape.
