1. A power rack attachment comprising:
a gearbox comprising a plurality of bearings and a plurality of gears, the plurality of gears being connected to a lead screw, wherein movement of the plurality of gears causes the lead screw to rotate;
a guide housing connected to the gearbox, the guide housing comprising the lead screw, a translating nut, and a guide rod, wherein the lead screw is connected to the translating nut, such that rotation of said lead screw leads to translation of said translating nut; and
a j-cup operatively connected to the translating nut, such that the translation of the translating nut causes corresponding movement of said j-cup.
