Abstract: A portable and collapsible aquatic abdominal exercising apparatus for use in a pool is provided. The apparatus includes first and second downwardly extending parallel leg members, first and second arm-rest extensions and first and second pool-deck supports. Each of these elements can be provided with telescopic capabilities. A single support rod extends between the two leg members and additionally supports a back-rest. A pair of four-way coupling units work to attach all of the elements together. The legs can move freely along two axis adding to its portability and collapsibility. The device sits freely in a pool and supports the weight of a user as the user rests their back against the back-rest, positions their forearms on the arm-rest extensions, grasps a pair of hand grips and repetitively moves their body upwardly to strengthen the abdominal muscles.

Abstract: Aquatic abdominal exercise apparatus having a pair of parallel tubular arms connected together by a first connecting member mounted over a pool deck surface juxtaposed to an edge of a pool. The arms extend downwardly along a side edge of the pool and then turn inwardly to space the apparatus from the pool wall. A second connecting member connects the portion of the arms extending downwardly and a back support is mounted on the second connecting member. A pair of arm supports project outwardly from the portion of the arms extending downwardly to provide hand supports for the exerciser.
