Key to Timing
Tennis can be delicate.
One day you are on, another out.
What is the most important key?
Provided your technique is quite decent, good timing keeps you in the loop; bad timing throws you off.
How do you ensure good timing?
You need to pause to find the ball.
You toss the ball up on the serve, you pause, accumulating power, and when the ball is on target, you strike.
You track the ball on your groundstrokes, it bounces, you pause, finding it, and you play it where you want.
At net, you track the ball with your hand, pausing while you adjust, and you place it with a full stop.
Beware of preparing early. You are too ready, tracking is poor, the pause too long, balance suffers, and mishits are galore.
