Abstract
A support is disclosed comprising a belt which encircles a wearer'"'"'s waist. The belt which is inflatable has an on-board inflation pump and may be used for weight lifting. The inflatable weight lifting belt includes a bladder defined by a single chamber having inflation and deflation mechanisms which allow the wearer to selectively adjust the amount of air in the bladder. The bladder has an oblong portion which is positioned on the belt so that when the belt is worn, the oblong portion is positioned adjacent to the wearer'"'"'s lower back for support. An elongated portion of the bladder extending through the aperture of the belt is integrally formed with inflation and deflation mechanisms on the other side of the belt. In the preferred embodiment, the inflation mechanism comprises a pump and a one-way valve and the deflation mechanism comprises an exhaust valve.
