Basically, these three kinds of boxing are used more. They all take the waist as the axis, and the waist drives the shoulders, and the shoulders drive the fists, and cooperate with the legs to concentrate on one point.
However, without the training of martial arts itself, it is a castle in the air, which is no different from putting on a show.
Physical quality, psychological quality, conscious response, etc. Without training, even if you master three boxing moves alone, it is difficult to apply them in actual combat.
Say self-defense is still free.
It's all gimmicks
Even if you train some fighting skills, if you don't have a few years.
You can't see any obvious effect in any martial arts. There is really something to do.
So don't expect to defend yourself.
During exercise
It is enough to improve one's psychological quality and physical quality.
