Sweet spot

Here's a way to start improving your balance right now. Let's tune into a reference point, the place on which you can feel your weight concentrated, the spot that will always let you know whether or not you are in balance. I call this reference point the "sweet spot" of your foot. The sweet spot is just behind the big toe and to the side of the ball of each foot (some people grow bunions on this point).

There are actually three sweet spots on a racquet's face. Each sweet spot measures a different physical characteristic of your racquet. The sweet spot that most of us think of is the place on the strings where the ball rebounds with the most power, or, technically, the post on the racquet with the maximum coefficient of restitution. The second sweet spot is where the least amount of shock is given to your hand and arm. This is known as the center of percussion. The third sweet spot is the node or place where the least amount of vibration occurs after the initial ball impact. Normally all three sweet spots do not occur in the same location.
