US Patent 10010756 Friction reducing assembly in an exercise machine

An exercise machine includes a frame and a movable element movably attached to the frame that is movable in a performance of an exercise. The exercise machine also includes a friction reducing assembly with a first part attached to the movable element and a second part attached elsewhere on the exercise machine. The friction reducing assembly includes a non-ferromagnetic material and a magnet that moves relative to the non-ferromagnetic material as the movable element moves. The relative movement of the non-ferromagnetic material and the magnet generate a force that reduces friction between the non-ferromagnetic material and the magnet.
