  • Patent number: 5669859
    Abstract: A multi-exercise free weight exercise apparatus which simulates free weight barbell exercise motions while preventing injury to a weightlifter. The weightlifting apparatus is comprised of a weight bar which rides on horizontal and vertical guide tracks and contains a safety catch mechanism device which latches onto pins located on upright brace supports should the weightlifter be unable to complete an exercise. The apparatus will allow a lifter to perform sophisticated exercises such as squatlifts, bench presses, deadlifts, and military presses in a natural free weight exercise motion while having the safety features of a non-free weight machine.
