Raising your game in the cardio stakes is easy. All you need to do is to load large muscle groups quickly, ask them to perform under pressure and give them just enough time to recover before you ask them to do it all again. The Cardio Rock workout utilizes relatively few exercises in quick succession to achieve just that. Get into the sweat zone and feel your muscles heating up and your body burning at a high level as you go through one exercise after another in quick succession with the Cardio Rock workout.
Extra Credit: 30 seconds rest between sets.
