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.

1. An exercise machine, comprising:a load for providing exercise resistance; a plurality of exercise stations; 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, the first pulley unit having a first side facing in a first direction transverse to said pulley axis and a second side facing in a second direction opposite to said first direction; a second floating pulley unit having a pulley housing and at least one pulley rotatably mounted in the housing, the second floating pulley unit being spaced in said second direction from the first pulley unit; a first cable linked to the housing of the first floating pulley unit on the first side of said first floating pulley unit; a second cable linked to the housing of the second floating pulley unit; and a third cable extending first around a first one of the side-by-side pulleys in the first pulley unit, then directly from said one side-by-side pulley around the pulley of the second pulley unit, and then directly from the pulley of the second pulley unit around a second one of the side-by-side pulleys of the first pulley unit, whereby a first length of said first cable extends up to said first side-by-side pulley, a second length of said first cable extends from said first side-by-side pulley to the pulley of the second pulley unit, a third length of said first cable extends from said pulley of said second pulley unit to the second side-by-side pulley, and a fourth length of said first cable extends from said second side-by-side pulley, each of said lengths of said third cable being located on the second side of said first pulley unit; and said first and fourth lengths of said third cable, and lengths of said first and second cables are selectively linked to said load and exercise stations.
