Whether you are just getting started with the fun and challenging sport of tennis, you are going to find that you are in a place where you need to start looking at your tennis technique. The skill with which you play the game can be greatly improved once you start working on your technique, and you will be surprised to see how much of it is simply keeping the right kind of attitude and being aware of what your body is doing.
First, consider what it means to look into bettering your tennis technique. Essentially, involves being aware of all the movements that you make that will affect the game. For instance, concentrate on your body the next time that you play. When you are preparing for the stroke on ground strokes, is the butt of your racquet pointed towards the ball? On the other hand, when your stroke connects with the ball, is the racquet parallel to the ground and is your arm well bent at the elbow? Is your body completely sideways to the ball when you are doing a one handed backhand?
Good tennis form is something that you will recognize if you have watched tennis. There is very real certainty and grace when someone's technique is good, and there is something clumsy and abrupt about someone whose tennis technique is off. Remember that you need to swing from the side of your body; in this fashion, you are going to be able to create a lot of energy and speed when you strike the ball. Remember that you need to think about the angle that your arm strikes the ball at.
It is next to impossible to improve substantially without good information at your disposal, and this is where getting online can help you. There are plenty of great resources on the Internet for improving your game, so take a moment and see what your options might be.
