Training bat having moveable internal weight and method

摘要

A training bat has a knob, handle section and barrel section. A weight is located within the interior of the barrel section on a rotatable shaft, and is moveable linearly. Linear movement of the weight is caused by rotation of the shaft. Preferably, the shaft is coupled to the knob, so that rotation of the knob causes rotation of the shaft and linear movement of the weight along at least a portion of the barrel section.
