This Ab Coaster is the base model for the Personal Series home market.
Redefining Abdominal Training
The Ab Coaster is a revolutionary exercise device that is taking abdominal training in a whole new direction. Unlike traditional crunches, which work your abs from the "top down," the Ab Coaster works your abs from the "bottom up," while limiting stress to your neck, back and shoulders.
Gymnasts and body builders have known this secret for years: to get a strong, lean core necessary for competition, they work their abs from the bottom up.
