What I like to do is stick the power drills segment of Cardio Kicks, replete with upper body drills, onto the tail end of Circuit Max after the last standing resistance cycle segment, and then sling a few more squats, plie squats and lunges on at the end of the power drills. In fact, I like throwing the power drills segment onto a lot of different workouts for a different kind of leg and cardio burn. Lub dem sequential power kicks and ice-breakers.
I do that mish-mosh a lot - probably too much, because I burn through athletic shoes like you wouldn't believe. But I still like it. And I like the upper body drills; even though there is no bag to punch, I like the discipline of controlled power in the throwing and stopping of each punch.
