Abstract: A truncated bat training device provides for training of the muscles and muscular strengthening of certain parts of the trainee's body. The bat has a 45 degree angle portion with a rotatable D-ring for attaching the bat to a fixed point. The angle portion projects to the backside of the upper body of the trainee and is turned toward the fixed point when the trainee swings the bat in a backward motion of a swing cycle in a resistance training mode. The angle portion provides a transition zone in which the D-ring rotates as the bat crosses perpendicular to the upper body allowing the trainee's wrist to accelerate with a ball at a simulated impact point where the trainee normally makes contact with the ball upon completion of the swing cycle. A ridge line teaches proper hand alignment, and several training techniques can be used with the training device.
