Cable Reverse Crunch

core / cable / machine

Connect an ankle strap attachment to a low pulley cable and position a mat on the floor in front of it. Sit down with your feet toward the pulley and attach the cable to your ankles. Lie down, elevate your legs and bend your knees at a 90-degree angle. Your legs and the cable should be aligned. If not, adjust the pulley up or down until they are.
