An apparatus includes a pair of support members, a cable, a rolling mechanism, a tackling bag and a pulley device. 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 cable from a first end of the cable toward a second end of the cable. 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 pulley device is coupled to the rolling mechanism and attached to the tackling bag. The pulley device is separated from the cable when the tackling bag is propelled from the one of the pair of support members toward the other of the pair of support members.
