Abstract: An apparatus for mounting to an exercise rack for vertically moving an exercise bar from a first location to a second location, which includes a lift bar, a lift cable connected to the lift bar, a cable retractor and retractor controls. The lift bar includes an elongate spacer having left and right end sections and a lift hook mounted proximate each of the end sections. The lift hooks releaseably engage the exercise bar. The lift bar then supports the exercise bar while it is moved from the first location to the second location and is then disconnected from the exercise bar. The cable retractor is connected to the cable and moves the cable to cause the lift bar to be moved between the first and second locations. The retractor controls are electrically connected to the cable retractor and are used by a user for controlling the operation of the retractor.
