Yes it's tough. I am an Intermediate aerobically(started exercising 6 months ago and intensely exercising 2 months ago) and Beginner with regards to weight training. Iused 3 and 5lb dumbells, and 1 lb for Susan's segment when they use soft weights. I do it in conjunction with a couple segments from 5 Day Abs and voila! a wonderful work-out. There is some high impact, and the first 2 times I did the tape my knees hurt afterwards, but now instead of running in place I jog in place and make other modifications as necessary to keep it low/lower impact. There is some toning - dips with weights, and one of Kai's segments has tons of arm work, so if you use heavier weights and control or slow the movements I'm sure you could get a decent total body work-out for a light strength day. I like it!

Instructor Comments:
Susan Harris is the best! To compare, she does a lot of high impact like Sandahl Bergman, but when she says "run and curl" several times, I wish the segment would never end. When Bergman says to "run and curl" I think "Not again!" Harris is very motivating and I am now convinced to get Vol. I, even though it is 12+ years old. The others are okay
