The King of the Hill trains pitchers to develop a directional force that creates a linear and efficient path towards home plate by creating an initial energy force starting at the ground through engagement of the lower half. This force, aka Ground Force, transfers up the legs, through the body, and out of the arm in a chain reaction, taking stress off of the pitching arm and increasing velocity. Instead of using verbal commands or visual aids, the trainer gives a feeling of directional force towards home plate with a return of an immediate audible feedback signal when done correctly. Once the player develops directional force that transfers throughout the body, they will challenge their ability by turning the lever at the back of the patented spring housing to increase the amount of force is takes to hear the audible feedback signal, which will result in higher velocity and consistent health of the pitching arm. The King of the Hill has multiple MLB and Collegiate endorsements stating that the trainer is a game changing device that trains the pitcher to engage the lower half.
