This brings us to the kinetic chain. What is the kinetic chain?
Simply put, it is the leg force (the source is the reaction force of pushing off the ground), which is transmitted to the crotch and waist, and the waist turns and the body moves (plus the force of coil, uncoil).
Waist stop (deceleration) to the shoulder, shoulder turn arm movement (plus arm strength), shoulder stop (deceleration) to the elbow, forearm, wrist, hand, head.
This involves the use of muscles and tendons, as well as the range of motion of joints, restrictions and so on.Modern biomechanics, especially the analysis of various sports, will consider how to establish an optimal way of power training.
To achieve the effect of certain actions most efficiently.

This is an ideal situation, and we should find ways to achieve it.Generally speaking, if you can stand in a good position to play the ball (can be a good loading), or serve, you should be able to fully launch the above power.
However, in some cases, the complete force is not allowed.
At this time, the force can also be exerted from the middle, such as some running shots.Perhaps only from the waist, or even only from the shoulder to start the force, but the basic use of power transmission should still be the same.The launch and transmission of this power is not only applicable to tennis, but also to many sports.Baseball batting, golf, even martial arts and so on.
In martial arts, strength also comes from the waist and legs.
If you only rely on the brute force of your arms, it is called clumsy force.
From the waist and legs, the integration of the strength of the whole body, from a point, is called "strength", strength.Although the details are different, the best use of strength in tennis is just like a kind of strength.Of course, you can also use only your arms and play with "stupid force".
You can also turn your hands and body in circles and play like a top.But if you want to be easy and graceful, but powerful, then you should practice the right use of force.
That is, the strength of tennis.
