Ab Crunch Machine vs Cable Reverse Crunch

Select a light resistance and sit down on the ab machine placing your feet under the pads provided and grabbing the top handles. Your arms should be bent at a 90 degree angle as you rest the triceps on the pads provided. This will be your starting position.

At the same time, begin to lift the legs up as you crunch your upper torso. Breathe out as you perform this movement. Tip: Be sure to use a slow and controlled motion. Concentrate on using your abs to move the weight while relaxing your legs and feet.

After a second pause, slowly return to the starting position as you breathe in.

Repeat the movement for the prescribed amount of repetitions.

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.

With your hands behind your head, bring your knees inward to your torso and elevate your hips off the floor.

Pause for a moment and in a slow and controlled manner drop your hips and bring your legs back to the starting 90-degree angle. You should still have tension on your abs in the resting position.

Repeat the same movement to failure.
