<p>A mobile arm, chest, and shoulder exercise apparatus to be used to train and condition participants in sports demanding a high degree of arm speed, endurance, and power. A harness which conforms to the user's upper back and sides and provides a path for elastic cords (80) through a system of pulleys (120) to a position adjacent the user's armpits, where hand grips (60) are attached to the ends of the elastic cords. When the user grasps the hand grips and directs them away from the harness, the resistive force of the elastic cords is transferred to the user's arms, thereby providing a relatively constant resistive force directed toward the armpits for strengthening the arms, chest, and shoulders. Generation of a nearly constant force is accomplished by directing one or more of the elastic cords to the rear of the apparatus (40), thereby allowing for the use of an increased length of cord. The apparatus may be adjusted to fit the physical dimensions of the user, and the resistive force may be varied to fit the needs of the user.</p> |
