A system has a weight having a base that has at least one pair of rollers provided at the rear end of the base, and a track having a wheel or rollers provided adjacent the front end of the track. The base travels along the track between a first position where the at least one pair of rollers is at the rear end of the track, and a second position where the at least one pair of rollers is adjacent the wheel or rollers of the track, with the track functioning as a stop element to limit the frontward motion of the at least one pair of rollers.
