Double Helix is a game of two halves. You work the lower body, transferring the load to the upper body and then you take it back to the lower body again and in all this time your core and abs are working hard. This is a full body HIIT workout that will get you in the sweat zone from the very first set. Go for the maximum rep count in each exercise use EC as a measure of your fitness level.
Extra Credit: Hit the same number of push-ups each time.
