Abstract
A racket swing training apparatus providing a user-chosen static positioning of a tennis racket in the hand, at angles to the forearm, which are determinable and repeatable. The device further provides components to set the face angle of the racket engaged to the device and visual indica to allow for the same positioning in subsequent uses. A planar member is removably engageable in a translatable engagement with a cuff adapted for engagement to the user's forearm. The planar member has an aperture opposite the cuff which is adapted to encircle the grip of a racket and sized to prevent rotation of the racket axis past predetermined limits relative to the axis of the planar member.
