A training bat has a central rod extending through the longitudinal length of the bat. A knob may be located at a proximal end of the bat. A handle located distal to the knob slides along the rod. A cone section is distal to the handle. The knob and cone section may limit the longitudinal sliding of the handle. A barrel section is distal to the cone section. If the barrel section includes an interior chamber, the distal end of the barrel section may include a removable cap. Weights and other objects may be located inside the barrel section. Electrical components or other devices may also be included in the cone section, barrel section or cap. The handle may include an acoustic chamber and an amplifying chamber to provide for emission of a sound when the bat is swung. The acoustic chamber and amplifying chamber may also incorporate safety features. |
