Abstract: A weighted sport training assembly used to overload the muscles while making sport specific movements during sport training. The principle can be applied to several sports implements such as a golfclub, a tennis or squash racquet, hockey stick, baseball bat, and other similar sports devices. The Golf Swing Training Club is an assembly of golfclub pieces and weights combined to offer an individual training a golf swing, or performing exercises that are either technical in nature, or fitness related, the opportunity to change the shape, length, or weight of the club by adding an extension shaft and inserting a variety of weights into the assembly.
