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 through a system of pulleys to a position adjacent the user\s armpits, where hand grips are attached to the ends of the eleastic 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, 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.

An exercise harness comprising: a back member with means for attachment to the back of a user, said back member having a rigid frame and plural plates slideably connected to said rigid frame for adjusting the end-to-end length of said back member to conform to the armpit-to-armpit width of the back of a user; two underarm members hingedly connected to the distal ends of said back member, each of said underarm members having means to adjust its end-to-end length to conform to the back-to-armpit width of the side of a user; two hand grips extending forwardly from said underarm members; one or more elastic members each having at least one distal end affixed to one of said grips for providing a force opposing movement of said grips, said elastic members having a length whereby said force is relatively constant over a predetermined range of motion of said grips; and plural low friction members affixed to said back and underarm members forming a path for said elastic members, said path having an end adjacent the armpit of a user, whereby said force is directed toward the armpit of a user.
