Playing badminton can make people practice "nimble eyes and quick hands". The reason is very simple.

The Harm of Playing Badminton Often at Night 3 Badminton Serve

1, station: stand near the center line of singles service, about 1 m away from the front service line. Stand steady and close to the serve line when serving doubles.

2. Preparation posture: the left shoulder of the body faces the net. When serving forehand, it is required to stand in a "T-step", with the left foot in front, the right foot behind and the center of gravity on the right foot. Hold the racket with your right hand, lift it to the right rear side, relax your elbow slightly, and hold the ball between your chest and abdomen with your left thumb, forefinger and middle finger. When serving, the body's center of gravity shifts from the right foot to the left foot (if you are used to playing with your left hand, the preparation posture is completely opposite).

3, grip method: four fingers together grip, thumb close to the club.

Badminton service method 1: Forehand service.

1. Forehand service essentials: When serving forehand, put the badminton flat on your chest with your left hand and look at the opponent's position with the corner of your eye, then let go of the badminton with your left hand and keep your eyes on the ball's falling route. At the same time, hold the racket in your right hand and wave your arm from top to bottom, so that the big arm can drive the small arm.

The racquet net should be pointed at the badminton head. When the badminton is about to fall in line with the racket net, the wrist will hit the badminton hard forward and upward. You can lift your heel slightly when hitting the ball, which is helpful for strength. When serving, the hitting position should not be higher than the hand and waist. It is illegal to throw the ball up and hit the ball in the air like tennis.

2. How to serve the ball high and far: If you want to send the ball to the backcourt near the opponent's baseline, you should increase the strength of your wrist, throw your right arm back as hard as possible, and then hit the ball forward and up high, so that the ball can run high and far in the air and fall in a nearly vertical direction when it reaches the opponent's baseline. This method of serving is called golf. If the service quality is good, it can effectively curb the opponent's performance of some technical and tactical levels. Generally used in singles competitions.

3. Method of serving a flat high ball: The difference between this service method and serving a high long ball is that it is faster and lower in height. At the moment of hitting the ball, the wrist exerts its force quickly, and the racket net surface and badminton form a large inclination angle (obtuse angle), allowing the racket to brush the ball and ensuring the ball to fly to the opponent's court quickly and low. This service method should pay attention to the fact that the ball cannot be easily received by the opponent, and serve in front according to the position.

4. Tennis method: The tennis method, as the name implies, is to serve close to the net. When serving, the action essentials are the same as above, but the strength and angle of serving should be changed, so we must grasp it well. That is, when the racket hits the ball, it should be slightly oblique and the wrist force should be uniform to ensure that the ball just crosses the net of the center line. The closer the ball is caught, the greater the lethality, because it is difficult for the opponent to catch the ball from the backcourt.

Badminton serve method 2: backhand serve

1. The action essentials of backhand serve are similar to forehand serve, except that backhand serve needs to twist the waist. When serving, put your right hand in front. After the left hand puts down the badminton, the right hand holds the racket on the left side of the body, and the right shoulder twists the body forward and backward. Similarly, hit the ball after seeing where it landed.

2, backhand serve high ball method: the same forehand serve high ball method, but pay special attention to the landing point is not easy to master, if the strength is too large, it is easy to hit the ball out of bounds. Therefore, when hitting the ball, we should grasp the strength, try to pick it higher, and don't hit it far, otherwise most of the balls that are far higher will be out of bounds.

3, backhand serve flat ball method: backhand serve has a feature: the serve speed is very fast, and the landing point is relatively tricky. Especially if you master the technique, try to hit the ball to the front of the net, fast, low, far and wide, that is, it falls near the boundary, leaving the opponent helpless. When hitting the ball, the inclination angle (acute angle) between the racket face and the badminton is small, which is just the opposite of the flat high ball, so the ball played in this way is a low flat ball with faster speed.

4. Backhand tennis: The forehand serve is the same. The same is true for mastering the strength. Don't push too hard. You can easily cross the net with a backhand flick.
