A method of executing a tennis stroke includes covering a knee of a tennis player with a knee pad during tennis play. The covered knee of the player is placed on a tennis court surface with the knee pad positioned between the knee and the surface. The tennis racket is swung toward a tennis ball so as to hit the tennis ball with the racket either while the covered knee is on the tennis court surface, or just prior to the knee contacting the tennis court surface.
