Cardio Crush will more than live up to its billing if you manage to bring your knees up waist height for all 40 seconds of High Knees and jump as high as possible during Jumping Lunges, Jump Squats and Burpees. The result is that within the first set you will be in the sweat zone and you will stay there until you come out the other side. Mind EC. It is important.
Extra Credit: Hit the same number of jumping lunges, jump squats and burpees every time.
