Put a new spin on your abs workout and power up your golf or tennis swing with this move that stretches your back, improves posture and strengthens your core and shoulders.
- Get into "tabletop" position on all fours with your knees directly below your hips and hands below your shoulders. With your neck relaxed, back flat and abs tight, look at a spot on the floor about six inches in front of your hands.
- Keeping your head still and lower body in place, twist your torso to the right and lift your right hand up and back toward the ceiling. Hold for three seconds, then lower your arm and return to starting position. To complete the rep, repeat on the opposite side, twisting your torso to the left and raising your left arm. Do two sets of 12-15 reps.
