The self defense application of Kung Fu vs. a COMPLIANT partner. Actually, there is no such thing as realistic fighting...unless it is a real fight. All other types of training and drills will have their limitations, even sparring. What is important is that you realize that training involves developing attributes within yourself. Attributes such as speed, power, timing, distancing and fluidity are important aspects to fighting while not actually fighting techniques themselves. I do train in bjj and submission grappling as well as Western boxing, so I am aware of both their advantages and disadvantages. In BJJ I am just starting out and I am a white belt. All martial arts including MMA have controlled compliant training in addition to sparring. I tried to show some of the counter punching techniques of kung fu, in a real fight for your life, one of the best ways to avoid having to counter against an unknown attack is to strike first, that way you do not have to know what hand they are going to throw first, whether they will feint, or even throw a kick. Over time I have had a lot of negative comments on my video which I always want to respond to.. but lately I have been trying to hold back because after looking at the channels of the people commenting, i never see any type of videos of them demonstrating their fighting technique. Trying to argue with these people is sort of like trying to argue with a 3 year old, no matter how valid my arguments are, I still lose because I would be arguing with a 3 year old.
