There are total body workouts that work all the muscles a little and there are others which work the whole body but pay particular attention to a specific group of muscles and then there's Aftershock. A difficulty Level IV workout that promises to make you vow to conquer it because it is a true challenge. Try it at the hardest setting you can (which really has to include EC) and come back to it time and again until you can truly master it.
Extra Credit: 1 minute rest between sets.
