Exercising device

A device for selectively permitting the user to do sit-up and back extension and lateral extension exercises comprising a horizontal runner, a foot support assembly mounted to said horizontal runner, said foot support assembly comprising a first feet confining means for holding the user's feet generally stationary while the user's feet are disposed upwardly in the sit-up condition, a second feet confining means for holding the user's feet generally stationary while the user's feet are disposed downwardly in the back extension condition, a third feet confining means for holding the user's feet generally stationary while the user's feet are disposed in a sideways direction in the lateral extension condition, a pelvic support member mounted to said horizontal runner spaced from said foot support assembly, means for rotating said pelvic support member to one of a plurality of selected operative positions, said pelvic support member having a generally flat surface for supporting the user's pelvis in the sit-up condition to comprise one of said operative positions, said support member having a second surface for supporting the user's pelvis in the back extension condition to comprise another of said operative positions, said support member having a third surface for supporting the user's pelvis in the lateral extension condition to comprise a further of said operative positions, at least one of said second and said third surfaces being rounded, a pair of spaced upstanding projections extending outwardly away from said third surface to form a saddle in which the user's pelvis may be positioned for minimizing any tendency of the body of the user to twist or roll while providing support therefor, said saddle including means for accommodating different sized users, and said foot support assembly and said pelvic support member comprising the sole means for supporting the user's body whereby the user's body is thereby otherwise unsupported to maximize the degree of flexion and resistance and range of motion during the various exercises.
