The SpringZBack Support Brace is designed to prevent or help relieve lower back fatigue and strain that can be caused by constant bending or lifting. The device's adjustable, spring-loaded chest plate engages with the chest to support the upper body while bending forward, thus transferring one's overhanging weight to the front of the legs. This transfer also reportedly assists the quadricep when in a squatting position to make it easier to lift with the legs, not the back. The SpringZBack Support Brace is designed to work from standing, kneeling, or sitting positions.
