ABSTRACT:
A practice bat for improving the swing of a bat used in a game such as baseball. The bat is hollow and has a moveable weight which moves between the handle end and the striking end of the bat. The weight may be held in the handle end by the squeezing of the top hand of the user's grip and, thus, is not properly released. In a relaxed grip, however, the swing of the bat causes the weight to move outwardly to strike the striking end of the bat. Preferably, the weight is held by making a portion of the handle end of the bat deformable so that it can be moved to press against the weight and hold it at the handle end.
