How do you know what type of grip to use in tennis?

There are a few different grips you use in tennis. The different grips include: the Continental Grip, Eastern Grip, Western Grip, Semi-Western Grip, and two-handed backhand grip. Let's start with the Continental Grip. You would use this grip when you are at the net hitting volleys and overheads. You will also use it when serving. You hold the racquet like a hammer with the "V" of your thumb and index finger on the narrower edge of the racquet grip. You'll want to use the Eastern Grip when you wish to hit ground storkes that are flat or have topspin. Hold the racquet with the "V" slightly off to the right. You'll want to use the Western Grip when you want to use extreme topspin. This grip is a preferred grip of clay court players because topspin rules on clay. The "V" extremely far off to the right. You'll want to use the Semi-Western Grip when you want to add power and you are a baseliner. You can either hit topsin or flat with this grip. The "V" is between that of the Eastern Grip and the Western Grip. It is recommended to have a Tennis professional demonstrate the different grips for you, so that you are doing them properly.
