Abstract
A cable and pulley assembly has a first floating pulley unit having a pulley housing and a pair of pulleys rotatably mounted side-by-side in the housing for rotation about a single pulley axis, and a second floating pulley unit having a pulley housing and at least one pulley rotatably mounted in the housing. A first cable is linked to the housing of the first floating pulley unit, and a second cable is linked to the housing of the second floating pulley unit. A third cable extends around one of the side-by-side pulleys in the first pulley unit, around the pulley of the second pulley unit, and around the other side-by-side pulley of the first pulley unit. The resistance on the first cable is then four times that on each section of the third cable, and plural pull points are provided for selective connection to exercise stations.
