ABSTRACT:
A body of limited compressibility, and uniform thickness, defines a support for the posterior of an exerciser during sit-ups, stomach exercises, and the like. A void in the body nestably receives the coccyx area of the exerciser. The body further has an extended member for supporting the exerciser's back, and an elongate void formed in the member comfortably receives the spinal length of the exerciser. Nodules line the edges of the elongate void; these repeatedly knead spine-attached muscles as the exerciser works, supine, on the body.
