Mark Verstegen's Core Workout—Week One
Workout B: Handwalk
Bend over at your waist and slowly walk your hands out into the pushup position. Keep your knees straight and then slowly walk your toes toward your hands. Do five reps. You should feel this stretch your hamstrings and it should ignite your shoulders and abs. Do five reps.
