Mostly Sane is exactly how you feel after doing this workout. This is a high-burn, VO2 Max-enhancing set of exercises that will make your heart pump and your lungs labor. Because you move large muscles, quickly you build up an oxygen deficit, much faster than you anticipate. The result is a workout that makes you feel all lathered up and totally at peace after it's all over.
Extra Credit: 1 minute rest between sets.
