I've done this workout a few times since I received it, and I enjoy it more and more each time.
There's a short warmup at the beginning and a short cool-down/stretch at the end of the workout, and you're going to do some serious work in between. You know how a lot of home workout DVD's claim the exercises will work both upper and lower body at the same time? Well, that's EXACTLY what you get here. Think pelvic tilts WITH chest flies while lying on your back, or rows PLUS leg pulses while standing.
The diversity is quite amazing, too: one background exerciser will show the beginner's version, the other one will do the intermediate version and Jeffrey will do the advanced moves. There's a VERY high repetition of each exercise (Jeffrey starts together with the two girls, then he goes back and starts explaining each version, which always takes some time, so that way it doesn't get boring), and the more times you complete the program, the more experienced you're gonna be, so you can do your own version of each exercise from the beginning if you feel like it. If you use heavier sets of weights, you can always make it more challenging.
Even though it's strictly a toning program, if you find your own level, I'm sure you'll end up doing some serious sweating (I know I have).
Altogether, it's great series of exercises, and I highly recommend it for anyone looking for a variable and tough workout.
