ABSTRACT:
A tennis aid for improving the stroke of a tennis player. The aid includes a wrist band for encircling the wrist of a tennis player and an associated elastic cord attached thereto. The cord is attached to the wrist band near its midpoint and at opposite ends thereof may be attached to the head of a tennis racket. When the handle of the racket is properly held by the tennis player tension in the cord will tend to prevent the player from bending or flexing the wrist during a tennis stroke.
