When serving, pay attention not only to the speed of the ball, but also to the rotation. Then, when we hit the ball along the edge of the racket frame, at the same time, we spin the ball inside. This method is suitable for players who need to adjust their grip or are adjusting it. Some people will form the racket pointing at the target when hitting the ball, but after holding the racket, they should change the habit of sitting on the racket face. In this case, it is driven by the edge of the racket, and then instantly rotates inward at the hitting point. Because pronation is done too early, it may be difficult for some people to understand. But during the whole process, the racket was pointed at the ball. Practice makes the serve spin more powerful. Let's look at two demonstrations to help us understand that the racket rotates in the direction of the swing and then rotates inward, instead of rotating inward at the ball prematurely.

Comparing the two examples, the example on the left is that the racket swings face up. At this point, the racket face has been opened, and it is difficult to control the ball. The example on the right is that the racket swings to the hitting point, and the racket always faces the ball. After the internal rotation hits the hit point, the rotation can be easier. The following is the practice method of pronation after swinging along the bar. We usually call this method "half-tube movement". It will be done in several steps. The swing trajectory is similar to a half-moon, first vertical, and then turn the swing face to the end. We will start with shooting. After the ball falls, we will shoot vertically along the trajectory of the half tube, and then rotate the shooting surface. We should try to avoid direct shooting. If we are used to half-pipe shooting, you will also notice the same movement and trajectory when serving. Professional circle column introduction: After careful arrangement, active tennis began to present a series of professional players' technical physical training, training competitions, competition highlights and interesting videos shot from special angles. I hope everyone will continue to pay attention to them!

A training session can accurately improve your serve power | What details can guarantee your serve power in the professional circle? There is no doubt that it is internal rotation. Many golfers know this truth, but they can't do it in practice. Is there targeted training for internal rotation? We need to learn an action and practice pronation! Step 1: Master the principle of air spin, stand with your feet open, raise your elbows to the position shown in Figure 1 (elbows should be two fists higher than your chest), then hold the racket and feel the forward spin with the strength shown; Step 2: Shoot the frame first, then the face.

Push the racket forward and upward with one side of the racket frame. Before hitting the ball, rotate the racket, the racket faces forward, pat the frame first, and then pat the face; Step 2: Practice In the baseline practice, you only need to throw the ball gently, and then practice according to the principle of "slapping the box first, then slapping the face". Note: 1. There is no need to add another turning point at this stage; 2. The racket is a straight line at the back;
