You will enjoy Low Impact Sweat. I only ordered that one and Rock/Sock. LIS is harder than I expected, but it's still very doable. I never feel like I can't complete any of the moves or reps, it's just that I find myself working harder than I thought I would given that it's intermediate, which is fine with me.
LIS is quickly becoming my "I don't feel like doing the workout I had planned for today and I can't really think of anything else I want to do" workout. I always add the Blizzard Blast to that one.
