I just did the Bootcamp premix from BMax2, and I have to say I love this type of format also. The only change I would make is to have most of the ab work be standing ab work (perhaps rotational type moves using a medicine ball?), so that we don't have to go from standing to lying on the floor and back up (the last segment can do floor work: chest, abs, etc.). (I also prefer to do the original BootCamp workout as "All but abs" followed by "Abs only" for this same reason.)
