Becky,
I am starting this rotation Monday also. I don't have LL but I am going to substitute GS Legs for it. I also don't have Step Works but I believe I'll substitute Step Jam for it. I'll have to read the descriptions to make sure it is a similar enough workout.
What w/o's do you have in the lower body and non-step aerobic area? I believe those are the categories you are looking for in the LL, L&G and KickMax area.
