A strong abdominal wall is your secret weapon. Not only does it make you feel good and look good but it becomes a performance multiplier in everything you do. Because the abs are used to transfer power from the lower body to the upper body and vice versa, a strong abdominal wall enables this to happen with the minimum amount of loss. When you have ripped abs, therefore, you run faster, lift better, feel stronger and look good naked. Totally unfair, right?
