The reasons behind the continental grip
The continental grip is the one we use to hold the racket for serves, volleys, and slices. This grip allows a player to hold the racket with his wrist aligned to the rest of his arm, allowing him to hold the racket firmly and to orientate the racket easily. This grip is bilateral, meaning we can use it for both the forehand and the backhand.
The continental grip is an ideal compromise to get started with tennis because it will allow you to learn to play while being relaxed, controlling your power, stability, and direction.
