At the beginning of practice, because the brain and body can't be completely coordinated (this is a process of finding strength, just like playing basketball at the beginning), it is necessary to warm up first, especially to stretch the shoulder ligament. Have you ever made a shoulder ring on the physical education class? Put your fingertips on your shoulders and draw a circle with your elbows. You must draw to the maximum, just like reaching for something far away with your elbow. The other is to put your left hand behind your head, pull your left hand as far as possible to the right with your right hand, then push your head back and hold on for a while; Usually, the shoulder straps are practiced less, and it is normal to be stiff.
Did you ever watch Wing Chun's punches or Bruce Lee's? The fist goes out from a lower position, and the fist is standing. You can use this as a link to find the strength to warm up and send it out with your shoulders. Don't pursue strength or speed. If your elbow hurts after playing for a while and you can't find it at all, adjust it again. When your elbows are less sore and your shoulders are sore, you will be on your way soon!
By the way, in actual combat, the drill is very similar to the hook in boxing. In terms of form and meaning, there is a saying that kung fu is on the back. It's not just about exerting strength, but also part of it means that the trunk needs to live. At a certain time, I practice holding two books on my elbows, twisting my trunk and punching. In actual combat, let the drill be more open, and don't stick to the usual posture completely, which is more powerful.
Hehe, I practice octupole boxing, and I also dabble in Xingyiquan, but I have more friends practicing Xingyiquan in Tianjin. We often exchange ideas and learn from each other's strengths, and we don't always know everything. I hope it helps you.
Xingyiquan should be water-based. According to five elements boxing's theory, the practice is the combination of step and boxing, which is powerful (this is the process of each boxing). At first, there was not much real strength, but it was all clumsy strength, and it was also a process of finding real strength by yourself. What is the practice? This topic is so big. I don't know which way. I can only say.
Tianjin, Hantu, nine generations and eight poles.
