Learn how to employ proper tennis footwork. This video demonstrates the tennis footwork split step.
The ready position is the position you want to be in when you're waiting for your opponent to hit you the tennis ball. It's the foundation for tennis movement in general. From this position you can employ the various footwork patterns that let you move around the tennis court correctly. The ready position is very similar to an athletic stance in basketball. Your feet are a little bit wider than shoulder-width apart, your knees are slightly bent and the weight should be on the balls of your feet.
Footwork is probably the most important part of tennis. Unfortunately, it is also one of the most underrated areas of the sport. Learning to move around the tennis court correctly is EXTREMELY important. Correct footwork lets you use correct stroke mechanics when you hit. Correct footwork is what typically sets advanced tennis players apart from everyone else.
Bringing your back foot up after you hit the tennis ball puts you in position to recover back to the middle of the tennis court. The key, as we explain in this video, is to get your body facing the net after you hit (similar to the ready position). This will let you side shuffle back to the middle of the tennis court.
The fourth thing that every high-level tennis player does when hitting a backhand is follow through. Extend out in the direction you are hitting the ball, then smoothly bend the elbows and wrap the racket up over your shoulder.
This video explains how the amount of shoulder rotation you get during a windshield wiper forehand can differ from a classic forehand. After you hit the tennis ball, you typically have to rotate a little bit more than you otherwise would on the windshield wiper. There are a number of reasons for this, but in this video we keep our focus relatively narrow.
Every time you hit a tennis forehand you choose how you position your feet -- what stance you will use. You can hit a forehand with an open, neutral, or closed stance, but you should stay away from the closed stance if possible. This last stance makes it difficult to rotate your upper body through contact, making it difficult for you to use correct forehand mechanics.
