Recruit is the workout that activates every muscle in your body and recruits several at a time to perform each exercise. The accent here is on form rather than speed. You don't need to explode when performing squats, for instance, but you do need to go deep and make sure it is a smooth, controlled motion throughout. This one will not have you breathing deeply at all but your muscles will definitely feel the load when you are done.
Extra Credit: do 10 push-ups instead of 4.
