In one sentence, describe what the following article is about:

Stand with your feet shoulder-width apart in front of the tee. Grip the club just above its head. Hold the club out in front of you in the starting position. Your grip doesn’t need to be perfect. As you swing the club, listen for the sound the club makes as you move it through the air. You should hear a whooshing sound. If you don’t hear a whooshing sound, then you are not swinging the club fast enough. See if the loudest part of the whooshing sound is happening before you hit the ball or as you hit the ball. Ideally, you should hear the loudest part of the sound at the bottom of the swing, where your club makes contact with the ball. If you hear the loudest part of the sound before you hit the ball, then that means you are throwing away your speed too early. Keeping swinging until you hear the loudest part of the sound at the bottom of the swing. If you keep hearing the loudest part of the sound before you hit the ball, then your wrists may not be bent properly. Make sure your wrists are bent properly to get the maximum leverage and speed.

Summary:
Hold a club upside down. Swing the club back and forth as if you are hitting the ball. Locate the loudest part of the whooshing sound. Practice swinging your club until the timing is right.
