  • Patent number: 4832336
    Abstract: A multi-purpose exercising device which comprises an elongated frame having coplanar top and bottom surfaces and front and rear ends. A pivotally mounted support post is mounted at the rear end of the frame for providing the dual function of holding a pad positioned on the top of the frame at an elevated angular position or extending from the bottom of the frame to provide a support for the rear end of the frame. A biceps femoris attachment is detachably mounted on the rear end of the frame for holding a leg pad parallel with and spaced from the rear end of the frame. This leg pad is pivotally movable by an exerciser lying prone on the frame with legs encountering the leg pad. A controlled resistance means is attached to the leg pad for providing a controlled resistive force to the pivotal movement of the leg pad.

  • Patent number: 4828255
    Abstract: A multi-purpose exercise bench employing two juxtapositioned elongated frames. A vertical support is provided for pivotally supporting one of the ends of the bench at a point above the base of an exercise device for movement from a substantially vertical position adjacent the device to a position extending laterally of the base of the device.A socket is mounted on the bench for detachably receiving above the bench a bench accessory. An extension member is provided for pivotally moving one of the frames relative to the other.

  • Patent number: 4746115
    Abstract: An exercising device utilizing a pneumatic piston and cylinder as the resistive element together with a force controlling mechanism that provides a continuously changing mechanical advantage throughout the course of the exercising stroke. Adjustment devices are provided for the control of both the magnitude and the rate of change of the resistive force as needed to achieve a constant apparent force. Convertible benches and accessories permit the practice of a wide variety of exercise routines using the exercise device.
