A device that straps against the front of one's pelvis and features chest and leg engagements extending from a central main-body to create a personal upper body support system. As wearer bends forward from the waist, the leg engagements leverage oppositely threaded shafts to screw together into an internally threaded main-body either against a powerful spring means used to effect a compressive stop or a spring-back counter force to the wearer's overhanging upper body weight. A knob-ended threaded rod screws through one of the shafts to adjust the point of engagement and/or spring tension. This device creates a prop effect between the wearer's chest and upper legs. The oppositely threaded shafts provide a unique mechanism that divides the transferred load equally to each leg regardless of leg stance, as well as for allowing unrestricted upright walking.
