  • Patent number: 5163889
    Abstract: A compact, portable foot/hand hold device used to perform sit-up, leg-raise and other type exercises with the help of any ordinary, interior, walk-through door. The device has two modes: "assembled" and "stored/travel". In the "assembled" mode the device provides a secure, comfortable foot and hand hold for the user while performing several type exercises. Constructed of three simple parts; an anchor, a connecting line and a foot/hand bar, the device assemblies in seconds. It is secured to the door by the anchor. For sit-up type exercises the user places his feet behind the foot/hand bar, one on each side of the connecting line, so that the bar is resting snugly but comfortably in the hollows above the insteps of the feet. His feet are necessarily positioned such that the heels are resting on the floor and the balls of his feet are pressed firmly against the vertical plane of the door.
