There's very little I don't like about this workout. It has it all: crazy-intense jumping, arm- and chest-blasting push-up variations, sprints, core-strengthening plank moves -- everything you could hope for in a quick, forty-minute workout.
My only complaint is that Cardio Power & Resistance is a bit too short. It ended right as I felt like I was hitting a groove. (I don't want to speak too soon, though -- I haven't yet tried out the longer "Max" series of Insanity DVDs, which are coming up in the second half of Round 2.)
