The SCRUNCH Accessory facilitates simple to advanced progression of abdominal workouts that lengthen and sculpt abdominals and oblique muscles. Differing from other ab crunch equipment, the SCRUNCH Accessory supports proper posture, stabilizes the upper body and engages the entire core musculature for a strong, lean mid-section. The unique positioning of this accessory enables closed-chain exercises that fortify muscles and bones. Opposite to a normal crunch done on the floor or on traditional crunch machines, user’s legs drive abdominals in every Scrunch for overall function and correct biomechanics. Perfect for any fitness level.
