  • Patent number: 5788615
    Abstract: A body extension exercise machine includes a frame, an elongated support connected to the frame and defining a reclined exercise position for an exerciser and a lever connected to the frame for pivotal movement about a pivot axis oriented transverse to and located below the support. A lower end of the lever includes a weight holder for holding a predetermined weight, and an upper end of lever includes a plate. When in the exercise position and reclined on the support, with at least one leg retracted and in contact with the plate, an exerciser pushes outwardly against the plate and against the held weight resistance to pivot the lever with respect to the frame from an initial at-rest position to a leg-extended position. Thereafter, the exerciser reduces the force applied to the plate and allows the lever to pivot back to the at-rest position, corresponding to the legs retracted position.

  • Patent number: 5554084
    Abstract: An abdominal hip/flex exercise machine includes a frame, a seat located at a first end of the frame for supporting an exerciser in an upright exercise position facing the second end of the frame, and a lever pivotally connected to the frame between the first and second ends thereof. At the second end of the frame, the lever includes at least one hub for holding weighted plates, while the opposite end of the lever located adjacent the seat includes spaced pads and handles adapted to be engaged by the arms and hands of an exerciser supported on the seat in the upright exercise position. The exerciser acts on the pads via a downwardly directed abdominal/hip flex motion to pivot the lever about the axis against the weight resistance held at the second end thereof. A leg brace may be included to restrain the exerciser from upward movement during performance of the downwardly directed flexing exercise motion, with the leg brace and the seat being vertically adjustable to suit the height of the exerciser.

  • Patent number: 5554090
    Abstract: An improved calf exercise machine includes a frame with a seat for supporting an exerciser in an exercise position with the legs extended horizontally, a lever pivotally connected to the frame in front of and below the seat, and an engagement plate secured to the lever and adapted to be engaged and acted upon by the upper portions of the feet of the exerciser via an outward toe extension movement followed by a rearward toe retraction motion. This movement arcuately rotates the lever about its pivot axis, with a corresponding flexion and then extension of the calf muscles. Weight holding hubs connected to the lever hold a selected number of weighted plates to provide a desired weight resistance to pivotal extension of the lever via the outwardly directed foot movement. This machine optimally isolates the calf muscles during calf flexion/extension.

  • Patent number: 5554089
    Abstract: A military press exercise machine for exercising the arms independently against a selected weight resistance includes a frame symmetric with respect to a midplane, a seat connected to the frame to define a declined exercise position for an exerciser, and a pair of levers with rearward ends pivotally connected to the frame on opposite sides of the midplane, above and behind the exercise position. Hubs located near the forward ends of the levers are adapted to hold weighted plates to resist upward movement of the forward ends of the levers with respect to the pivot connections. Handles located adjacent forward ends of the levers are adapted to be grasped by an exerciser in the exercise position and then raised upwardly in a military press motion against the weight of the plates. During upward movement, the handles move toward the midplane. When the arms are extended, the handles reside above the pivot connections of the levers.

  • Patent number: 5273505
    Abstract: A high row exercise machine includes a frame symmetrical with respect to a vertical midplane, a seat connected to the frame adapted to support an exerciser along the midplane in a forward facing direction, and a pair of spaced levers pivotally connected to the frame above and behind the seat on opposite sides of the midplane. The levers pivot through vertical planes of motion which converge with respect to the forward facing direction of the seat. Each of the rearward ends of the levers is adapted to hold a selected weight resistance, and each of the forward ends of the levers includes an angled handle located in front of and above the exerciser supported on the seat. An exerciser supported on the seat reaches up and grasps the handles, with palms facing forward, and then pulls downwardly and slightly forwardly in a high row exercise motion to pivot the levers against the selected weight resistances held by the hubs.
