A cable exercise device includes a vertically movable weight stack, a rotatable spool assembly, first and second cables, and a movable exercise implement. The rotatable spool assembly is located proximate the weight stack, and comprises spaced apart large and small cable spools affixed to a common rotatable spool shaft. The first cable has a terminal end attached to the weight stack and a winding end attached to the small cable spool. The second cable has a winding end attached to the large cable spool, and extends from the large cable spool to a terminal end. The movable exercise implement is secured to the cable exercise device by the terminal end of the second cable, and is adapted for being employed by a user performing an exercise.

1. A cable exercise device, comprising: a vertically movable weight stack;a rotatable spool assembly mounted proximate to said vertically movable weight stack, and comprising spaced apart large and small cable spools affixed to a common rotatable spool shaft;a first cable having a terminal end attached to said vertically movable weight stack and a winding end attached to the small cable spool, the winding end of said first cable adapted to wind onto and unwind from the small cable spool on a first side of said common rotatable spool shaft upon rotation of said rotatable spool assembly;a second cable having a winding end attached to the large cable spool and extending from the large cable spool to a terminal end, the winding end of said second cable adapted to wind onto and unwind from the large cable spool on a second side of said common rotatable spool shaft upon rotation of said rotatable spool assembly; anda movable exercise implement secured by the terminal end of said second cable, and adapted for being employed by a user performing an exercise, whereby positive displacement of said movable exercise implement when lifted causes said second cable to unwind from the large cable spool thereby rotating said rotatable spool assembly while simultaneously causing said first cable to wind upon the small cable spool, such that said first cable lifts said vertically movable weight stack vertically from an initial at-rest position to an elevated position. 2. The cable exercise device according to claim 1, wherein said vertically movable weight stack comprises a plurality of individual weight stack plates, each of the plurality of individual weight stack plates having top and bottom major surfaces and sides extending between said top and bottom major surfaces. 3. The cable exercise device according to claim 2, wherein each of the plurality of individual weight stack plates defines a central shaft opening formed between the top and bottom major surfaces, and a central pin opening formed through at least one side of said sides and communicating with said central shaft opening. 4. The cable exercise device according to claim 3, and comprising an elongated selector shaft attached to the terminal end of said first cable, and adapted for extending through the shaft openings formed within said plurality of individual weight stack plates. 5. The cable exercise device according to claim 4, and comprising a weight stack pin adapted for inserting through the central pin opening of a selected weight stack plate of the plurality of individual weight stack plates and into an aligned one of a plurality of longitudinally spaced pin holes formed with said elongated selector shaft. 6. The cable exercise device according to claim 1, and comprising a floor anchor, wherein the terminal end of said second cable is attached to the floor anchor. 7. The cable exercise device according to claim 6, wherein said movable exercise implement comprises an elongated hollow bar having a cable-entry end and an opposing cable-exit end, and first and second bar guides located at the respective cable-entry and cable-exit ends, and wherein said second cable extends through said elongated hallow bar and outwardly from the cable-exit end towards said floor anchor. 8. The cable exercise device according to claim 1, and comprising first and second vertical guide rods adapted for guiding vertical movement of said vertically movable weight stack between the initial at-rest position and the elevated position. 9. The cable exercise device according to claim 1, wherein the large cable spool of said rotatable spool assembly comprises a plurality of circumferential grooves adapted for controlling overlap of said second cable when winding upon and unwinding from said large cable spool. 10. The cable exercise device according to claim 1, wherein the small cable spool of said rotatable spool assembly comprises a plurality of circumferential grooves adapted for controlling overlap of said first cable when winding upon and unwinding from said small cable spool. 11. The cable exercise device according to claim 1, and comprising a self-standing rack with cooperating extensions adapted to temporarily hold said movable exercise implement at a desired elevated position. 12. A cable exercise device, comprising: a vertically movable weight stack comprising a plurality of individual weight stack plates, each of the plurality of individual weight stack plates having top and bottom major surfaces and sides extending between said top and bottom major surfaces;a rotatable spool assembly mounted proximate said vertically movable weight stack, and comprising spaced apart large and small cable spools affixed to a common rotatable spool shaft;a first cable having a terminal end attached to said vertically movable weight stack and a winding end attached to the small cable spool, the winding end of said first cable adapted to wind onto and unwind from the small cable spool on a first side of said common rotatable spool shaft upon rotation of said rotatable spool assembly;a second cable having a winding end attached to the large cable spool and extending from the large cable spool to a terminal end attached to a floor anchor, the winding end of said second cable adapted to wind onto and unwind from the large cable spool on a second side of said common rotatable spool shaft upon rotation of said rotatable spool assembly; anda movable exercise implement adapted for being employed by a user performing an exercise, and comprising an elongated hollow bar having a cable-entry end and an opposing cable-exit end, and first and second bar guides located at the respective cable-entry and cable-exit ends, and wherein said second cable extends through said elongated hollow bar and outwardly from the cable-exit end towards said floor anchor, whereby positive displacement of said movable exercise implement when lifted causes said second cable to unwind from the large cable spool thereby rotating said rotatable spool assembly while simultaneously causing said first cable to wind upon the small cable spool, such that said first cable lifts said vertically rotatable weight stack vertically from an initial at-rest position to an elevated position. 13. The cable exercise device according to claim 12, wherein each of the plurality of individual weight stack plates defines a central shaft opening formed between the top and bottom major surfaces, and a central pin opening formed through at least one side of said sides and communicating with said central shaft opening. 14. The cable exercise device according to claim 13, and comprising an elongated selector shaft attached to the terminal end of said first cable, and adapted for extending through said central shaft openings formed with said plurality of individual weight stack plates. 15. The cable exercise device according to claim 14, and comprising a weight stack pin adapted for inserting through the central pin opening of a selected weight stack plate of the plurality of individual weight stack plates and into an aligned one of a plurality of longitudinally spaced pin holes formed with said elongated selector shaft. 16. The cable exercise device according to claim 12, and comprising first and second vertical guide rods adapted for guiding vertical movement of said vertically movable weight stack between the initial at-rest position and the elevated position. 17. The cable exercise device according to claim 12, wherein each of the large and small cable spools of said rotatable spool assembly comprise a plurality of circumferential grooves adapted for controlling overlap of said first and second cables when winding upon and unwinding from the respective large and small cable spools. 18.
