Abstract: This invention is a baseball training apparatus, which attaches to the lower torso by way of a four inch wide VELCRO belt. It has an adjustable arm support for proper positioning of the back arm and to insure that he batter develops not only a correct swing, but also a consistent swing. The arm support adjust at an equal rate for a variety of torso and upper arm lengths at a 45 degree angle in such a manner that 1 inch vertically will equal 1 inch horizontally. The apparatus is designed to teach a proper swing, but not a proper stance, being that the apparatus is connected to the torso, it allows for a full range of motion for the batter, since adjusting his stance is determined by the batter's own sense of balance as the batter moves, the back arm stays in the correct position.
