ABSTRACT:
A portable exercise device for strengthening abdominal muscles is provided which can be operated by an individual exercising on a mattress and box spring, or the like combinaton, without requiring additional assistance during the exercise routine. The device may be easily unfolded for use, and following use, it may be refolded and conveniently stored. The device at one end is folded for securement between the mattress and the box spring, and unfolds and overlays the upper portion of the mattress for use by the individual. The device is adapted to fold and conform with the user's bent ankles, knees and hips, and these folds correspond to the fold lines for folding and unfolding the device. Foot securement means are employed to stabilize the user's feet, and this eliminates the need for assistance during the exercise program. The device at the opposite end lies on the mattress and includes a sheet material upon which the user rests, and the weight of the user on the sheet anchors the device on the mattress and prevents it from slipping or becoming displaced during use.
