Abstract: An improved exercising device includes a footboard on which an exerciser may stand and a pair of continuous loop elastic bands attachable to the footboard and being positionable over the exerciser's shoulders. A back harness is selectively attachable to the elastic bands to facilitate their retention over the exerciser's shoulders, while the footboard is provided with angulated slots for retaining the continuous elastic bands. Additionally, a base member is attachable to a bottommost portion of the footboard so as to prevent the elastic bands from rubbing against a ground surface, and elastic retaining loops are positionable between the slots to further retain the elastic bands in engagement with the footboard.
