Main Muscle: Abdominals

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.

Caution:

For this exercise, always select a weight that you can easily handle as using too much weight can easily lead to injury.

Review: Ab Crunch Machine	Exercise Rating	3/10
Dec 26, 2009 7:04 AM: The abs need a full range of motion to be worked most efficiently. Depending on the machine, you may not be able to get a full stretch before contraction.
