The rocker system of the Ab Roller supports the weight of the head, neck, and upper body while mimicking spinal flexion, making it easy for people of any fitness level to perform an effective abdominal crunch.

This Ab Roller comes with a "Pro Assist Spring" attached to the head rest, which gives you the option to work your abs with a slight boost. It is great for assisting your workout when you are sore or just need help on that last set of crunches.
