One of the sections has a handle fastened to it to facilitate transporting the device in the folded condition. One of the sections has fastened to it a strap or device which can be used to fasten an individual's legs or other body parts to the platform during the performance of "sit-ups" or other exercises requiring or facilitated by the fastening of an individual's legs or other body parts to the platform. One of the sections contains an adjustable torsion spring mechanism connected to pulleys, cables, and handles fashioned in a manner to offer an adjustable resistance to an individual's muscular movements as he pulls on the handles. The aforementioned three sections are padded to increase the individual's comfort as he exercises.
