It is comparable to P90x according to the American Council on Fitness. There is no cardio workout and you sub in your own cardio routine. I like that flexibility.
I have tried two of the dvd's to get a sense of the moves and exercises. So far I am impressed with the thoughtfulness of the design and the instructional style. My quads were sore after the first day. It focuses on functional fitness (full body).
Don't let the macho bravado of the trailer dissuade you. Georges is actually a good natured guy and, along with this trainer, is very motivating. Plus, he is working and sweating right along with the group. At the end of the workout, he offers his closing words of wisdom.
