Abstract
A racket grip training apparatus providing user chosen static positioning of a tennis racket in the hand at angles to the forearm that 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 to the user's forearm at a first end and has an aperture at an opposite end 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.
