Mark Verstegen's Core Workout—Week Two
Workout B: Handwalk—Reverse
Bend over at your waist and put your hands on the ground. Walk your feet backward until you are in a push-up position. Keep your knees straight and walk your hands toward your feet. When you feel a stretch, walk your feet back out and repeat. Do five reps.
