I like to keep my workouts at 50-60 minutes. KPC's premixes give me several options to do that since the main workout runs over an hour. The intermediate intensity drills are a nice transition from the warm-up to the rest of the workout. Once you hit the high intensity drills and continue through the combo's, your heartrate is up there throughout. I didn't like Kick Max because the combo's were too pivoty (had to leave out the pivots on carpet) and not very intense. Then the blast section was off the charts, then to be followed by the leg drills which were boring to me. The whole thing seemed like bits and pieces and not well done as a continuous workout.
Legs and Glutes is great in it's own right. Lots of variety - weighted work, no weights, plyo moves, floorwork. Cathe and crew are smiling through the pain. They're having fun and so am I.
