Abstract: Exemplary exercise racks can include a frame having a variety of support elements. The frame can support first and second movable vertical supports that are horizontally movable within the frame. A movable purpose bar can be attached to the first and second movable vertical supports such that the movable purpose bar can be moved vertically along the movable vertical supports. The movable purpose bar can therefore be moved vertically, along the movable vertical supports, and horizontally, as the movable vertical supports are moved horizontally within the frame. The purpose bar can include an attachment point for receiving one or more of a variety of attachments, which can be used for performing a variety of different exercises. Movement of the movable purpose bar and corresponding attachment point can configure the rack for a variety of uses with a variety of attachments.
