Cardio Shock is all about defying gravity. Using your body like it's made of something way lighter than it is, commanding it to do your bidding and forcing it to take to the air like gravity doesn't exist. Go as high as you can during the Jump Knee-tucks (and remember to land on the balls of your feet) and move as fast as you can in the Jumping Jacks (maintaining the ball of the foot contact). Add EC for that extra load to your lungs (to help push you to a fresh level).
Extra Credit: 1 minute rest between sets.
