The at least one arm assembly includes a pivot mount couplable to a rack member of the weight rack, where the pivot mount is height adjustable on the rack member relative to a ground surface; a main arm couplable to the pivot mount, where the main arm is adjustable relative to the pivot mount along a longitudinal axis through a length of the main arm; and a weight attachment couplable to the main arm, where the weight attachment is adjustable relative to the pivot mount along the longitudinal axis through the length of the main arm. A handle attachment and/or a combination weight and handle attachment is couplable to the main arm, each being adjustable relative to the pivot mount along the longitudinal axis through the length of the main arm.
