Abstract: A training device for use in teaching proper hitting mechanics includes an elongated, narrow beam, a rear foot support slidably coupled to the rear end of the beam, and a wedge-like front foot support fixedly mounted onto the front end of the beam. A longitudinal slot is formed in the rear end of the beam to restrict displacement of rear foot support along a three-inch linear path. To facilitate displacement of rear foot support, the beam is provided with a pair of removable glide strips constructed of a self-lubricating, low-friction plastic material. Rear foot support includes a balance plate that teeters relative to a base plate in contact with the glide strips. The ability of the balance plate to pivot and slide relative to the beam trains a hitter to utilize the proper sequence of connected movement between the lower and upper body using both sensory and auditory feedback.
