ABSTRACT:
An apparatus, kit and method for stretching and strengthening the muscles of the lower back and legs of a person. The apparatus includes a backboard and a belt to restrain the person's pelvis. A single cable is provided with sliding handles, a pulley guiding system, and leg supporting slings. In a stretching exercise segment, the handles are slowly pulled by the person to raise the legs and thereby stretch the supporting muscles of the spine. In a strengthening exercise segment, the person's feet are pushed toward the floor against the resistance provided by the muscles of the arms.
