    Abstract: Methods and apparatuses for training athletes are described. Specifically, in one embodiment, a wooden baseball training bat is shown. The training bat permits development of fundamental swinging techniques by using weights that are strategically located along different axial locations of the training bat. The training bat's knob-loaded design forces the hands to stay inside the ball during the swing, and to prevent casting and other mechanical breakdowns.
