Tennis serving is a major in difficult technical problems

The outside corner of the first zone is mainly to pull the opponent off the court by spinning.

The position of the flat contact and the side spin contact ball is not the same.

But don't change the body or the route of the throw.

The outside corner contact ball should be at the position of nine o'clock, and then the racket swings to the right to draw an arc, and then the racket continues back to the left, and the flat contact ball should be the position of the table.

The topspin is in the middle of the 6.

The ball should preferably rotate above the head.

It is recommended that you can watch the side spin of the federer in the first zone) but if you need to add some strength.

Naturally, the ball points slightly to the right.

Because you need to reach the ball to use the strength of your body.

This adds a lot of speed.

Just look at Djokovic's serve.

Both of these two have a good spin on the side in the first area.

It is possible to distinguish the inside and outside corners by changing the throwing point, and there is no need to pursue a high degree of consistency of movement like a professional player. And even professional players can't do it, the throwing point is absolutely the same, so Moya and Agassi can judge the direction of the opponent's serve by throwing the ball and play the iconic kick sever

If you can tolerate the pain of being slapped on your calf, you can practice left-handed serve.

The center of gravity cannot fall, and should be kicked up in the direction of the shot, that is to say, the inner and outer corners are mainly controlled by the direction of the center of gravity (whether it is to kick up and not jump, and the center of gravity should follow up to the field).

It's better to find someone to teach.

You're talking about Zone 1, right? The outside corner kick should be thrown a little to the right, and then the paddle surface rubs the ball with a cutting feeling, but the contact time is not too short, so that it is easy to contact the ball about one or two points on the net, and it is good to practice more, in fact, the best way is to find a coach who understands, and you can understand it with two sentences. If you still don't understand it, practice it well.

Coordination of the serve is important and difficult, and you can look at Coach Nick's sonic serve training.

1. In the amateur game, there are indeed some strange players who rely on the lower serve to get points, because their lower serve is very stable, there are almost no double faults, and the ball bounces either surprisingly high or surprisingly low, so that the opponent wants to pick up the force but is easy to make mistakes.

2, it is rare in professional games, because after all, the speed of the lower serve is too slow, but it is not excluded that occasionally break the rhythm and use the lower serve to score, the most classic is the sudden start of the French Open in 89 Zhang Depei vs. Lendl, and finally won the championship, note that it is "suddenly". If you keep using the underhand serve, I don't think you will be able to win the first round of the French Open, and I don't think you will be able to win the amateur senior tournament.

Simplicity and, above all, the strength of the penalty and serve.

The serve is the only technical event in tennis that is completely controlled by oneself and is not restricted by the opponent, so it can maximize the technical characteristics.

1) Tennis grip Continental or Oriental backhand grip.

2) Prepare to relax your whole body, stand sideways near the midfield mark outside the end line (singles), with your left shoulder facing the left net post, facing the right net post, your feet about the same width apart, your left foot about 45" from the end line, your right foot about parallel to the end line, and your center of gravity on your left foot. Hold the ball in your left hand and lightly hold the racket at your waist, pointing your head forward. Breathe evenly and concentrate your mind.

3) The ball throwing and the back swing throwing and the back swing racket action are synchronized, and the thumb, index finger and middle finger of the ball holder gently hold the ball and shout the ball, palm up. When the racket is drawn down and backwards, the player lowers to the right leg at the same time, and then when the racket swings in a large arc from behind the head and the body turns, bends the knees, and spreads the shoulders, the ball holder gently lifts the left foot in front of him until it is stretched above the head. The ball should be tossed in a coordinated and steady manner, and the ball should be sent to the highest point and then thrown into the air with the fingers.

At this time, the right elbow is abducted back about the same shoulder height, the head is pointed to the sky, the left waist and hip are bowed, and the center of gravity of the body begins to move to the right foot with the toss, and then smoothly begins to move forward. This ant is violently engraved, and the shoulder is at right angles to the net.

4) Hitting the ballWhen the left hand throws the ball, the racket continues to swing upward, and then the elbow joint of the grip hand is relaxed, so that the body that rotates forward and the right shoulder automatically make the arm produce a perfect circle (note that the racket is not deliberately called to do the back scratching action). When the ball descends to the point of impact, quickly swing the racket upwards to hit the ball, push up with the left foot, so that the arm and body are fully extended, when the body stretches forward and upwards to hit the ball, the shoulders and arms have been rotated, and the shoulders are parallel to the net. When swinging the racket to hit the ball, holding the racket wrist to drive the forearm to have a "whipping" action in the spin, which is the key action of the serve, and it is also the sum of other forces such as moving the center of gravity forward, kicking the leg, turning, swinging the racket, etc.

5) After the ball is released, tilt the body into the court and maintain a continuous and complete forward and upward stretch movement. Swing the racket to the left side of the body (the American spin racket swings to the right side of the body) and move the center of gravity forward to follow up and maintain balance in a completely natural way.

Personally, I think that the reason why tennis serves so easily makes mistakes is that it is difficult to grasp the strength and direction of the tennis serve, which is why it is so.

Because tennis players want to hit aces that dominate the enemy, this kind of ball has a lot of power and has a particularly tricky angle, so it is easy to make mistakes.

That's because the tennis ball is fast and impactful at the moment it pops up, and at the same time, the ball spins in the air, causing the direction to deviate.
