ABSTRACT:
A basketball shooting training aid for releasably limiting to a predetermined maximum length the span distance between a basketball player's shooting or launch hand and guide hand comprises a pair of elastic wristlet bands secureable around opposite wrists of the player. Each wristlet has protruding outwardly therefrom a flexible, longitudinally elongated stalk which has at the outer end thereof a coupler releasably engageable with the other coupler. In a preferred embodiment, each coupler includes a permanent magnet having a longitudinally outwardly extending magnetic field of opposite polarity to that of the opposite coupler, thus enabling the couplers to automatically engage when outer ends of the stalks are brought sufficiently close to each other, e.g., about 2 inches, and to automatically disengage when a tensional parting force of a predetermined value, e.g., about 6 pounds is exerted on the couplers by drawing the wrists apart.
