Power Cardio uses large muscle groups to load the lungs, push the VO2 Max and raise the pulse rate for a truly high-burn session that works most of the body. Raise your knees to waist height during High Knees, keep your body perfectly straight during push ups and Plank Crunches and EC for that extra level of difficulty and you will know it when you're done.
Extra Credit: Keep the plank transitioning from push-ups to plank crunches.
