Detail one: body weight drop

Just like the long jump, you can only jump farther if you use your legs to exert force.

Serve is also, as the first link of the serving power, the leg must bend the knee to use the power. In addition, improving the height of the hitting point is also here to contribute.

Detail two:  When kicking the ground and exerting force, it is also the time to turn the head.

Before the swing, the arm is relaxed, and at this time, with the help of the upward force of the body, it is natural to “turn the head of the racket”, which is more conducive to the relaxation of the arm and the borrowing of the back.

Detail three: When swinging upwards, the racket face is parallel to the swing direction

Doing this will make your swing faster, but it will be followed by pronation of the forearm

Most of the friends who are serving the ball generally shoot forward with the racket facing the ball, rather than hitting the forearm internal spin at the end.

Detail four: The trajectory of shoulder movement is from bottom to top

Many friends have no speed or power to serve, mainly because the shoulders are rotated out on the horizontal plane.

Look carefully at the picture below. During the entire shoulder movement, the key force time is that the shoulder is turned from bottom to top. This is very beneficial to the acceleration of the head from bottom to top!

Detail five:During the serving process, keep the balance of the body.

Looking at Federer’s serve above, in the whole process of serving, the body is in a balance (dynamic balance).

A simple method is to move the main force of the serve upward, and part of it forward. The specific proportion will change due to the height and the desired effect. Generally, amateur golfers can use more force to go upward.

The key point at this time is internal rotation of the forearm.
The rear view at the moment of hitting is as follows:

Detail six: Don’t bow your head too soon.

If you bow your head too early, it is easy to serve the net. Players with this problem can look forward after seeing the racket touching the ball, which can effectively reduce mistakes.

Detail seven: Fix your hitting spot

Find the correct hitting spot first, then keep it in mind, and fix it with practice. To serve well in a tense game.

Detail eight:

No matter the first or second serve, rotation is essential. If there are too many mistakes in one serve, you can use the enhanced version of the second serve as the first serve. It is also a very good choice to replace the first serve with a good placement and fewer mistakes.
