Atomic Push Up with Crunch: Step 1
HOW TO DO IT: Kneel facing away from the anchor point with your feet in the foot cradles, place your hands on the ground slightly wider than shoulders width and lift up to a plank position. Lower your body toward the ground by bending your elbows to 90 degrees. Press back up, lift your hips slightly and crunch, bringing your knees to your chest.
TIP: Be sure to lift your hips slightly before doing the crunch.
