I have one simple question. I practice martial arts at home and I learn from some online tutorials. My question is: how can I improve my punching speed ? P.S. If you know where I could find some good tutorials on the net, please tell me.
Not such a simple question. If the answer was simple, all boxers would have super fast punches.
Punching speed is directly related to the acceleration of the arm. To increase the acceleration, and thus the speed, of an object, you have to decrease the mass of the object and/or increase the force that is applied to the object. In the case of a punch, the object is an arm. It is not practical to try to decrease the mass of the arm, but it helps to avoid increasing its mass by unduly increasing the size of the arm muscles. The primary propelling force of the arm is the shoulder muscles, so, to increase the acceleration and speed of a punch, you want to increase the explosive power of the shoulder muscles. If you notice boxers, they have very large, well-defined shoulder muscles and relatively small arms. This gives them greater punching speed and the smaller arms are an asset when they have to hold them up for 30 minutes during a ten-round fight.
To increase the explosive power of your shoulder muscles, do lots of pushups and do all variations of them so you work all the muscles. While doing pushups, use perfect form and make a full range of motion, even if you can only do a few at a time. Over time, the number you can do will increase. For a few pushups in every set, explosively push off the floor so that the hands leave the floor. In good variation of the pushup is to do them on the fists, with the fists held in the position that your martial art uses, and then explosively push up off the floor in the same manner used in punching.
Then work long hours punching on a speed bag, shadow boxing, and jumping rope. Punch while wearing arm weights or while holding small weights. Practice punching, using perfect form and moving in slow motion while fighting against your own body’s resistance. Use isomeric exercises while sitting at your desk at work or at school.
I do not remember any specific web sites that show punching techniques. Free martial art information is difficult to find on the Internet. Everyone wants you pay for their expertise and the time, effort, and money spent putting the information on the web.
WOW, I must admit I didn't expect you to answer me this quickly :) You are really great. Thank you for your advice, I will do my best to follow it. Best regards from Bosnia and Herzegovina.
