It takes just 270 seconds to transport you from the Earthly plane to the special world of Hell Week and the Hellraiser workout is your ticket to that place. Stay on the balls of your feet when you perform High Knees, bring your knees to waist height each time and pump your arms as you run. The core and abs exercises also require perfect form. You can add EC if you like but that's just like adding sugar to cream. It's pretty good either way.
Extra Credit: 1 minute rest between sets.
