Abstract: Two embodiments of an exercise device are described and include a track along which a slidably mounted transducer moves as a user pulls a handle attached to a cable. The transducer is biased toward one end of the track by a force produced by a rope and pulley attached to weights or a set of elastic tubes. The cable passes through the transducer and anchors to the other end of the track such that the transducer is slid toward the other end of the track against the force when the handle is pulled. In a first embodiment, the track is curved. In a second embodiment, a linear track is rotatably mounted to provide angular adjustment and two slidable transducers are slid inward from each end of the track as the user pulls on respective cables.

Abstract: An improved lower extremity exercise device has a planar bed and support members which form a channel and storage chamber. An elongate support member is positioned below an edge of the bed and forms a shoulder. The elongate member includes vertical sockets and horizontal apertures. Tubular pegs are inserted in the sockets and apertures in sequences selected by the user. Elastic bands are looped around the pegs and portions of the body for the performance of exercises. The shoulder provides a proper heel-resting surface for certain exercises. A slidable bar is positioned in the channel and can be moved outwardly and secured at a pre-selected extension. The outward end of the bar is also engageable with elastic bands and allows additional exercises to be performed. The improved device is portable and provides storage for pegs and bands.

Abstract: An exercise apparatus for more specific full range muscle development. The apparatus includes at least one weight, a guide for the weight and a pulley affixed to the weight. A line is reeved through the pulley and one end of the line terminates in a handle by which the line can be grasped by a person utilizing the exercise device. The other end of the line is anchored. The weight is free to move on the guide when a force is applied to the handle. Since the pulley is affixed to the weight, the weight moves as the exercise device is utilized and the direction of application of force constantly changes.
