Claim:
A tennis skill training system, the system consisting of: a foot placement platform and stroke training device, said foot placement platform consisting of a substantially planar member having a top and bottom surface, said top surface of said member including foot placement graphics disposed thereon, said foot placement graphics consisting of a first stance position representing right and left foot positions for a right-handed player proximate a first court area, a second stance position representing right and left foot positions for said right-handed player proximate a second court area, a third stance position representing right and left foot positions for a left-handed player proximate said first court area, a fourth stance position representing right and left foot positions for a left-handed player proximate said second court area, a first toss target representing a first forward foot post-stroke position for said right-handed player, and a second toss target representing a second forward foot post-stroke position for said left-handed player, said stroke training device consisting of a grip emulating a tennis racket grip, said grip being sized for being held by a user when employing said device for training, a single flexible and extendable umbilical having first and second ends, said first end being attached to and emanating from said grip, said umbilical being capable of stretching and extending along its axis approximately 1 in from an initial unstretched length, and a first fixed weight attachable to said second end of said umbilical, said first weight having a weight in the range of approximately 13-15 oz, whereby when said first fixed weight is attached to said umbilical and said device is subjected to rotational motion in a vertical plane by a user's arm said device generates a first angular momentum, whereby said umbilical stretches from first at-rest length to a second extended length, and whereby said device exerts an outwardly directed first force on said user's arm that tends to extend said user's arm.
