Li Cai was in the national tennis team, and after testing it, he picked three people to take away for a week-long tennis coaching.

The three people that Li Cai took away, one is naturally Xu Feng, who once sparred for himself, the other is Wu Di, who abstained in the first round in the magic capital Masters, and the third is Zhang Ze, if there is no Li Cai's appearance, Zhang Ze and Wu Di are the tennis "first brother" of Huaguo.

When they came to Li Cai's private tennis court, except for Xu Feng, the other two were amazed, feeling that Li Cai's training ground here was even better than that of the national team.

Zhang Ze thought in his heart: "It is worthy of being the first tennis player who has won the annual Golden Slam, the world's No. 1 tennis player, and the private tennis courts are so good, I must work hard, learn some superb skills in this week, improve my tennis strength, and strive to achieve good results and win glory for the country." ”

As for Wu Di, although he was also shocked, he thought in his heart: "I must work hard and fly solo as soon as possible, so that I can have money, like Li Cai, to have such a good private tennis court for training, and to hire the best trainer and coach." ”

Although Zhang Ze and Wu Di both want to work hard to improve their tennis strength, both of them have different ideas, Wu Di's selfish distractions are too heavy, if it is the same study, Zhang Ze's future achievements will definitely be much better than Wu Di's.

Because the system is being upgraded, Li Cai can't check their potential value, and can only judge what style of play they are suitable for based on his tennis experience in the past few years.

Through a day's time, various measurements and tests, Li Cai also roughly knows the tennis strength of these three people.

There are many tennis skills, and the skills related to the hand involve serve, receive, topspin, downspin, high-pressure, volley, etc., and there are also related skills in the fast movement of all directions on the foot, broken step control, and sliding step.

Although Li Cai is proficient in tennis movement and tennis skills, these are all given by the system.

After all, many things can only be understood but not spoken.

And Li Cai is not a person who is good at expression, you can ask him to show it, but if you want him to explain, it is estimated that it will be GG.

However, Li Cai also knows that compared with European and American tennis players, Asian tennis players have disadvantages and advantages in physical talent, the advantage is that the reaction speed will be more agile, the body coordination will be better, and the foot movement ability is also very flexible, but the disadvantage is that it is naturally inferior to European and American tennis players in terms of strength and explosiveness.

Although many people feel that they are not as good as Europeans and Americans in terms of physical fitness, they are not.

Many Asian tennis players have poor physical fitness, and they will not be able to play at the back of the tennis ball, so they will not have the strength to lose the game, in addition to the reason of physical talent, but more importantly, because there is no high-level systematic training.

After Li Cai entered the professional tennis game, if he did not have the blessing of systematic talent, Li Cai would have a big gap with adults in terms of physical fitness because of his age, but Li Cai himself has improved greatly after high-level systematic training, which is enough for him to finish high-intensity tennis matches.

Therefore, Asian tennis players can only be compared with European and American athletes after high-level systematic training, even if their physical talent is not as good as that of European and American tennis players.

Therefore, after this week, Li Cai handed over his own serving skills to them.

In terms of serving skills, Li Cai is very strong in both flat serve and topspin serve, belongs to the top, and has his own unique style.

Although Li Cai can also teach them their own pre-net skills, but the pre-net skills are too talented after all, and the current tennis style is not suitable, and Li Cai can't teach them a lot in a short time.

So it's good to teach them what they're good at.

On the tennis court, Li began to show the trio his serve and details.

The quality of the serve, the ball play a key role, and the height of the ball should not be too high or too low. The position should be appropriate, and at the same time, the shot should be as smooth as possible when throwing the ball, the more crisp the action of throwing the ball, the better, such as hooking fingers, throwing wrists, etc. are redundant small actions for throwing the ball, which may affect the stability of the ball after throwing, and the less rotation of the ball in the control, the better, if it is completely non-rotating straight up and down is the most conducive to serving.

At the same time, the best time to throw the ball out of the hand also has requirements, the best point of the ball out of the hand is the highest point of the palm rise, if the ball is too early, it is easy to cause the ball to rotate or shake in the air, affecting the stability of the ball, if it is sold too late, the ball will move to the direction behind the player's head, and it is not easy to follow-up serve.

And the position of the ball also has an impact on the serve, generally if the position of the ball is forward, the force after the ball is served will be greater, and the speed will be faster, but the hitting point will also be forward, and it is not easy to grasp the landing point. It's easy to get out of bounds, so if you want to use a more aggressive serve, move forward with the toss.

On the contrary, if the throwing position is lower, the success rate of the serve will be higher, and it is easier to control the rotation of the ball and control the landing point of the ball, and it is easier for the opponent to return the ball, so if you choose a more stable and conservative serving strategy, you can throw the ball further back.

Of course, for beginners in tennis, they will understand it at the beginning of learning tennis, so Li Cai will not teach them the basics.

It's just that when it comes to throwing the ball, it's different for everyone.

The hand holding the racket will begin to swing back, when the racket swings to a certain angle, it will take the elbow as the axis, the forearm, hand, and racket will show the appearance of hanging down to the back, and at the same time, because the knee is bent at this time, it looks like the body is like a "bow", the angle of this swing is not clearly defined, most of them vary from person to person, and the height, hand length, grip habits, etc. are affected.

So after letting them see their serve clearly, let them practice on their own, and watch and guide by themselves.

The tennis ball does not rely on the strength of the arm alone, but the power of the whole body, driving the racket in the hand to swing to the hitting point, and the final power explosion point is just the moment when the ball is hit.

Li found that among the three people, only Xu Feng did the best and was also the most talented.
