Of course, boxing has a long history with a recorded history of 5,000 years. Olympic events and boxing rank first in all fighting events. After practicing boxing, the impact will advance by leaps and bounds, and your fragile parts, such as your head and neck, can't even touch your opponent. Boxing needs to practice skills and improve physical fitness. Physically, the back of the leg, waist and abdomen are the most important, and the shoulders and arms should also be practiced. The thigh is responsible for the output of strength, and the size of the blow mainly depends on the thigh, so exercising the thigh is mainly to improve the absolute strength. The waist and abdomen connect the upper and lower bodies into a whole, which can output a large part of strength, but the most important thing is endurance. If the waist and abdomen can't rotate, the leg strength can't be transmitted. Back muscles determine the speed of punching and closing, slow down the beat, and can also output a lot of power. Leg endurance must be strong, attack and defense must rely on the pace of movement, jumping can not survive the target. Shoulders can provide a small amount of hitting power, but endurance is the most important thing. In boxing, if you hit the back, you can't raise your hand and take it away. This means that you can't hold your shoulders. The biceps brachii can output strength in the swing of hook, and the triceps brachii can output strength in the straight fist. What the arm needs most is speed, the speed of punching and the speed of closing. Practicing boxing is more than enough for self-defense, because there are not many people who love sports in life, and even fewer people fight. Beer bellies are all over the street, and most of them are in poor health. If you want to reach a higher level, I suggest practicing judo or Brazilian Jiu Jitsu. These two are needed for ground warfare. You only know boxing. In case you meet a professional trainer who fights with you in close combat, you can only be beaten if you can't fight. Very skillful, isn't it, brother? I like to mix martial arts and boxing. I especially like Roy Jones, golovkin, Tai Sen and Pacquiao. I'm from the countryside. Please discuss with me if you have any questions. Take me in. Thanks, man.
