  • Patent number: 7597654
    Abstract: Moveable exercise benches are disclosed. In one embodiment, an exercise machine includes a load, an exercise station, and a force-transferring assembly operatively coupling the exercise station and the load. A moveable support is positioned proximate the exercise station and is adapted to support a user during an exercise. The force-transferring assembly is adapted to allow the moveable support to move without decoupling the force-transferring assembly from the exercise station and to allow use of the exercise station at any location of the moveable support without adjustment. The force-transferring assembly may be a cable-and-pulley assembly. In an alternate embodiment, the force-transferring assembly may be adapted to apply a counter force on the moveable support that at least partially counters a reactive force applied by the user to the moveable support during the exertion of the exercising force.
