ABSTRACT:
A tennis training device is provided which has a head portion comprising a lightweight plastic foam material, a handle member and a grip affixed to the handle. The overall weight of the tennis training device is distributed so as to simulate the balance of a conventional tennis racket. The grip includes finger placement guides so oriented as to train the player in the eastern forehand type of grip. The air resistance of the head when swinging the tennis racket forces the player to utilize shoulder action in his swing thereby conditioning the player in proper tennis form with an objective of minimizing one of the contributing causes of "tennis elbow." When used in conjunction with a lightweight spongy game ball, the tennis training device is particularly suited for indoor use. Additionally, a retaining device is provided attachable to the handle of the tennis trainer and adapted to receive a companion game ball.
