  • Patent number: 7452311
    Abstract: An exercise machine includes a dual fulcrum articulated force lever connected to a machine frame. The articulated force lever includes a first force arm and a second force arm. A fixed end of the second force arm is pivotally connected to the frame at a first fulcrum. A movable end of the second force arm is pivotally connected to a first end of the first force arm for pivoting of the first force arm about a second fulcrum. A resistance load is attached intermediately to the first force arm. A handle section is connected to the first end of the first force arm opposite the pivot connection to the second force arm. Movement of the handle section in one direction rotates the first force arm and the second force arm together about the first fulcrum against the load. Movement of the handle section in an opposite direction rotates the first force arm about the second fulcrum against the load.

  • Patent number: 7291102
    Abstract: An exercise apparatus includes a floor engaging base, a vertical stanchion, and at least one body support. Cables are interconnected between respective handles and respective pivot arms. At least one resistance device is interconnected between the pivot arms and the frame. The cables are routed about pulleys on the frame in a manner that facilitates different types of exercise motions. Adjustments to resistance may be made by repositioning at least one of the cables and the resistance device relative to the pivot arms.

  • Publication number: 20050239616
    Abstract: An abdominal exercise device comprising a semi-rigid member, an upper member and a lower member is disclosed. The upper member and the lower member couple to the semi-rigid member, the upper member and lower member can be securely or detachably attachable to the semi-rigid member while the lower member can have pivoting capabilities. Feedback may be provided in a visual as well as a physical form to allow a user to determine whether the device is properly being used and optimal results are being achieved while performing the exercises.

  • Publication number: 20050164856
    Abstract: The present invention is a method and apparatus for performing Pilates exercises. The apparatus includes a bench defining a plane. The bench has a main body portion and a head portion operatively connected to the main body portion. The bench is adapted to support an associated user. The main body portion is adapted to remain stationary relative to an associated underlying surface during performance of an exercise. The apparatus further comprises an upwardly extending frame operatively connected to the bench. An adjustable pulley assembly is operatively connected to the frame, and is adapted to receive an associated resistive band. The adjustable pulley assembly is adapted to be selectively movable along the frame.

  • Patent number: 5709638
    Abstract: A strength training exercise apparatus includes a frame having a generally upright back rest portion, and a generally horizontal seat portion, and further includes opposing arm members pivotally mounted to the back rest portion of the frame. The arm members are movable through an arcuate range of motion, and include locking pins for selectively locking the arm members in desired angular positions. The apparatus still further includes a resistance assembly consisting of a fixed anchor mounted on the frame, a movable anchor which is movable relative to the fixed anchor, and a plurality of elastomeric resistance cords releasably secured between the movable relative to the fixed anchor to provide resistance to movement of the movable anchor.
