Hand Walks

Walking your hands back and forth sounds like a piece of cake. But check out where Totton's knees are in the video: up in the air, as if he's about to launch himself out of his shoes. By walking your hands away from yourself, you're creating an unsteady base, meaning your abs have to work that much harder to keep you stable. If you aren't feeling a burn (good for you, man) try walking your hands further from your body.
