Abstract: The Tennis Stroke Trainer is designed to allow one person to practice any type of tennis stroke and follow through of the racket at any height chosen. Each model purchased determines what height is used. The Tennis Stroke Trainer is designed to be used indoors at one's home or office but can be used anywhere. The Tennis Stroke Trainer is the combination of a metal spring of desired size cohered to a rod of desired length which on the other end of said rod is directly cohered to a tennis ball, thus comprising the entire moving part of this apparatus. The designed angled positioning of said spring in the spring mount which is attached to the base provided is at angles ranging from twenty to eighty degrees from horizontal, thus creating the desired action of the moving ball.
