A back support apparatus. The apparatus is fabricated with human dimensions including a torso harness (12) and two resilient leg strap assemblies (16) which terminate at and attach to a user's shoes. The harness (12) includes shoulder straps (22), a front strap (24), waistband clips (32), and a lumbar-supporting cincture (14). Positioned behind each leg of the user, the leg strap assemblies (16), include thigh straps (34), resilient members (20), ankle straps (40), sliding adjusters (42), and shoe clips (44). The waistband clips (32) attach to the user's waistband in front while the shoe clips (44) attach to the user's trailing shoe tops. The flexible torso harness (12) firmly embraces the user's upper body while the flexible leg strap assemblies (16) conform to the buttocks and legs. The lumbar-supporting cincture (14) braces the lower back of the user by its firm encirclement of the lumbar region but maintains flexibility with a multi-strap design vested in abdominal straps (28). Resilient members (20) stretch as the user bends over and consequently exert a downward pulling force on the rear side of the torso harness (12). This force results both in tightening the lumbar-supporting cincture (14), and in helping to lift the user in front.
