Query: a bit brief

While I do like the concept of Cardio Boot Camp and I do enjoy the enthusiasm of Tracey Mallett and her moves, I believe this workout with it's 3 brief segments, doesn't give ample time for a real workout. I find myself fast forwarding through the warmup of the following section in order to maintain the momentum of the cardio intensity. A much longer cardio routine, with less segments would work great. The other drawback of this video, is the warmup and especially the cooldown section, is almost non-existant. These things are crucial, especially for a beginning exerciser, who doesn't know what to incorporate to bring the heartrate down when the cardio section is through. These few additions would make this video good. I do like Tracey's combinations and she keeps you psyched throughout.
