ABSTRACT:
An exercising device is designed to exercise precisely the muscles, and groups of muscles, used in throwing a ball, such as in pitching a baseball. A simulated ball has a line fixed thereto, the line passing over a pulley, then receiving weights. The weights are designed to nest together to prevent relative movement therebetween. A bracket is fixable to an interior doorway to carry a pulley for directing the line for exercise. In exercising, one grips the simulated ball in the manner of the real ball, and exercises by moving the arm in the same manner one would throw the ball, thereby exercising exactly the same muscles and groups of muscles used in the sport represented by the simulated ball.
