HIIT workouts are all the rage and Run And Gun doe snot disappoint. It is fast, light, uses every major muscle group there is and gets you in the sweat zone within the first three minutes (set 1). The question after that is just how much can you push yourself so you can improve faster? Can your knees go higher during High Knees? Can you pump your arms more? Can you punch faster? can your hooks be sharper and your upper cuts driven by your bending your knees more? These are questions you get the chance to find the answer to.
Extra Credit: 1 push-up every 20 seconds.
