ABSTRACT:
An abdominal exercise device and method is disclosed that is capable of isolating desired abdominal muscles. The present device is preferably made of bent tubular steel and is configured in a double U-shaped configuration whereby a user rests his/her neck on a fixedly adjustable neck support crossbar between opposing U-shape members and rests their upper arm regions on opposing armrests or on an A-frame structure above the user's head. The device is fixedly adjustable along various lengths by telescoping means that permit adjustment of the device to fit different physical morphologies and configurations. Moreover, armrests and hand grips are pivotally and/or rotatably mounted in order to accommodate personal comfort while using the present device. The present method relates to the use of the present device to strengthen abdominal muscles without injury to a person's spine and neck by alleviating undesired contraction of other abdominal muscles, such as the psoas muscles, and by maximizing isolated abdominal muscle contraction due to the unique cam design of a ground contracting member.
