Concentrated Crunch with Swivel

Lie faceup on a mat. Bend your legs and lift your feet so that your calves are parallel to the ground. With your arms extended at your sides, crunch to lift your shoulders from the floor. Next, reach your left hand toward your left ankle as you drop both knees toward the right. To complete one rep, repeat on the other side by dropping your knees to the left and reaching your right hand toward your right ankle. Do two sets of 10 to 12 reps. -Oxygen Magazine
