Abstract: A training brace is provided for retaining the position of an arm of an athlete. The brace comprises mating first and second arm engaging members, means for securing the members together and to the arm, and stop means for limiting the position the arm of the wearer may achieve. The members are preferably concave and each include a section which engages the upper arm and the forearm and which when connected, surround the arm. The members are hingedly connected along one edge, and are securely mated to surround the arm of a wearer with connecting straps which encompass the members. Stop means are provided for preventing the forearm and upper arm of the wearer, as measured at the elbow, from achieving an angle of greater than about 90 degrees.
