Off The Grid is the kind of workout that prepares you for what happens when the Zombie Apocalypse arrives and you have to run, climb, duck, carry heavy stuff and fight. It's a high-burn full body workout that recruits all of the major muscle groups for a challenge you feel right from the first set. Add EC because it pushes you to your limits faster plus if we are talking survival in a post-Apocalyptic landscape, you know you ought to. Right?
Extra Credit: 1 minute rest between sets.
