The following video clip is a great demonstration of drill used in Wing Tsun Gung Fu called sticky hands (A.K.A. chi sao) to develop close quarter fighting skills such as efficient short range punching, knees and elbows, sensitivity/tactile awareness, trapping, structure in movement, comfort in that range. Some Wing Tsun practitioners use this drill as a form of close quarter sparring.
This exercise is primarily used to develop forearm to forearm sensitivity. The martial artist performing this drill is a World Famous Wing Tsun Master by the name of Emin Boztepe.
I have had a chance to train with him a few times and had the privilege to cross arms with him. This guy is truly amazing, and I can attest that he is one of the most amazing martial artist that I have ever seen or experienced in person.
Even though you may say to yourself, people don’t fight like that? Your right they don’t, again it’s a drill and trust me it is extremely helpful during a real life situation, IT WORKS!
Most street fights end up getting into that range quickly. Even when you watch Boxing or MMA, notice that the fighters usually end up in clinch 9 times out 10, unless someone can control distance by keeping people out in striking range or they are able to close the gap quickly and take someone to the ground.
Chi Sao training in is paramount in JKD training, if it’s not part of your training, it should be.
