A good serve is the key to being a good tennis player. There are two ways to "hit up" on the ball for a great serve. You can swing up towards the ball (as shown in the second picture) by reaching up and hitting down. Or, you can literally hit the ball up (as shown in the first picture) by extending your arm and hitting up.
The toss can decide whether or not your serve makes it in. To make a good toss, swing the ball straight up in the air, with a straight arm. It needs to have exact timing for it to land inside the lines. Your arm should be straight and you should rotate your shoulder joint upward for a good toss and serve.
The windup in a tennis serve is very critical to hitting a good shot. As players toss the ball up into the air, their feet press against the court creating ground reaction forces to build elastic energy. It is critical to rotate legs, hips, and shoulders to produce maximum angular momentum. Data shows the clear importance of rotating the hips, legs, and shoulders.
