In this lesson, Coach Ken DeHart emphasizes the importance of eye coordination, breath control, and focus during tennis rallies. Players practice a drill where they must count each shot before hitting, helping to regulate breathing and improve focus. The session also incorporates competition, encouraging players to compete while refining their forehand and topspin techniques. By limiting players to one ball at a time, Coach DeHart introduces a sense of urgency that enhances concentration and precision. The goal is to train players to maintain composure and perfect their skills under pressure.
