An apparatus includes a pair of support members, a cable, a rolling mechanism and a tackling bag. The pair of support members are fixedly coupled to a surface. The cable is attached to and extends between the pair of support members. The rolling mechanism is connected to the cable and configured to traverse the rod from a first end of the rod toward a second end of the rod. The tackling bag is attached to the rolling mechanism and configured to be propelled from one of the pair of support members toward the other of the pair of support members. The rolling mechanism is permitted to move relative to the cable when a force is applied to the tackling bag.
