Good timing is a key to playing well. A suitable playing rhythm comes naturally to players who grew up with the game. It is more difficult to achieve for an adult learning tennis.
Many novice players stay too close to the baseline, preferring to accumulate points by hitting short-distance balls. However, this reduces the time available for hitting the ball, and causes muscle contractions that interfere with overall technique. Stand about two or three yards back from the baseline. Doing so gives you time to adjust to an incoming shot and allows you to use more of the court. As a bonus, you will have less reason to worry about hitting too long, since the opponent's baseline is further away. If you’re new to the game, avoid playing solely for points; this will help you in the long run.
Following these suggestions can help you find an effortless rhythm of hitting the ball as it descends. This will in make the game that much more enjoyable.
