Queen of the Hill Standard Model Watch Video to train with the same aid the MLB & D1 National Champions Vanderbilt trains with!!! Queen of the Hill - Softball Through consistent reps, the Queen of the Hill will aid in accomplishing the following: Improvement of mechanics Gradually increase the leg drive toward home plate Improved upper body’s ability to accelerate and rotate Faster arm speed and higher velocity at the release Reduced stress on the pitching arm With the immediate audible feedback, it becomes easy for the athlete to acknowledge the feel of using the lower half and producing ground force to drive towards home plate. Once the player has mastered the technique of utilizing their legs and producing leg drive, they can gradually increase the resistance which will challenge them to gradually increase the amount of leg drive used resulting in higher velocity. The Queen of the Hill trains pitcher to develop a directional force that creates a linear and efficient path towards home plate that results in a long radius stride length. This force, aka Ground Force, transfers up to the legs, through the body, and out of the arm in a chain reaction, taking the stress off of the pitching arm and increasing velocity. Many players reference this chain reaction and the force created as Leg Drive. Instead of using verbal commands or visual aids, the trainer gives a feeling of creating leg drive and driving directly towards home plate with a return of an immediate audible feedback signal when done correctly. Once the player develops leg drive consistently, 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. With repeated reps, the pitcher will create muscle memory that will cause her to do the same in the game. Weight 21 lbs Dimensions 15 x 17 x 2 in
