Abstract: To assist a tennis player in maintaining a proper grip on the handle of a tennis racket, a training aid is disclosed which includes a wristband, a racket-handle band and interconnectable strap segments separately attached to such bands for tethering the racket handle to the wrist to force the player to hold the head of the racket above the wrist, and thus forcing the handle of the racket to assume a proper angle with respect to the player's forearm. The strap segments are provided with interconnectable/separable fabric fasteners, such as commercially available "Velcro" (a trademark) fastening strips for quick and easy connection and separation using the hand that is not holding the racket, and the bands and strap segments are made of a lightweight material which does not add perceptible weight to the racket or to the player's wrist, permitting the player to wear the training aid without discomfort or interference.
