ABSTRACT:
A training bat for ball games is shown as including a handle, a ballast, and a ballast adjustment structure. The ballast adjustment structure further includes an adjustment stem attached to the handle, and ballast attachment structure connecting the ballast to the adjustment stem. The handle, stem and ballast are attached coaxially to one another, and the adjustment stem includes external thread convolutions formed along its axial length adapted to provide selective adjustability of the ballast relative the handle along the longitudinal axis of the bat. The selective adjustability of the ballast is provided by rotation of the ballast relative the handle while the handle, adjustment stem and ballast are integrally attached.
