Your head is the heaviest part of your body. If your head moves a great deal, you can throw your body off balance.
A still and quiet head is important in baseball hitting, golf, tennis, shooting a baseketball, bowling, hockey, billiards on and on and on.
A still head also allows your eyes to focus well.
So, make sure your head remains still and see if doing this improves your performance at your favorite sport.
