Automatic Rebound Belly Wheel, Abdominal Exercise Machine, Six Pack Machine, With Double Wheel Design

he ab roller is an excellent exercise for working the upper body musculature too, including the erector spinae, the stabilizing muscles running the length of your spine, the latissimus dorsi (or lats), the broadest muscles on each side of your back, and your deltoids (shoulders), chest, biceps and triceps. The lats and shoulders are stimulated primarily during the rolling out phase, while your core is worked during the secondary, rolling back stage. Remember, a stronger core benefits the body's daily function in many ways, such as torso rotation and flexing, as well as protecting your spine.

How to use

Steps for perfecting the ab roller:

1. Kneel on a mat and place the ab wheel in front of you, directly under your shoulders.
2. Before you start moving, contract the core by drawing in your belly button up toward your spine, keeping the spine neutral and your back flat.
3. Grab onto each side handle and keep your arms straight and stabilized, before slowly rolling the ab wheel out with control.
4. Pause just before you feel your back will arch, and slowly return to your starting position by rolling backward, activating the abs the entire time.
5. Continue to work on a fuller range of motion by extending your hips further as you gain strength.
