A training grip that can be installed onto a tennis racquet handle for positioning a tennis player's hand or hands correctly on the racquet to teach or train the player individual tennis strokes. The training grip is adapted to be easily and removably installed onto the eight-sided handle of a tennis racquet directly over an existing grip that is permanently affixed to the racquet. The training grip is an elongated cup having a slit that runs lengthwise from the first end of the grip to the opposing second end of the grip and through the bottom of the grip through which the grip may be installed onto the racquet handle. The outer surface of the grip is molded to have ridges and depressions creating contours for receiving and positioning the player's fingers and thumbs of the player's hand or hands. The grip is used to teach or train the player on the proper hand positioning for various methods of holding the tennis racquet commonly used to achieve various tennis strokes including the Continental Forehand, the Semi-Western Forehand, the Western Forehand, the Eastern Backhand, and the Two-Handed Backhand.
