Hi,
I just put the weight segments in order of the workouts - mostly because it didn't require much thinking to do it that way! I skipped the ab/plank/core segments in workouts 2 and 3, and just do the ab and planks from workout 5 (from SJP). The whole series takes 37 minutes. I think the time I added the ab/plank/core sections from workouts 2 and 3, the time was 52 minutes.
Here's a good post from VF that has the breakdown of the chapter and title information:
