Now we are talking about single punch and not chain punches.
Thanks for putting up those clips. With those clips, it's much easier to discuss the WC power generation method. If we look at this clip, we can observe 2 things.
- When he punched out, his fist, arm, shoulder, body, and back shoulder are not lining up into a straight line. In other words, his body did not turn to the maximum. If we consider the body turning as "compress" and the final punch as "release". IMO, he did not "release" fully at the end of his punch. If he can turn his body more, his punch will be more powerful.
- He did not take advantage on how to pull back his previous punch and use it to generate more power into his next punch. In other words, he did not take full advantage on his "compress". The farther that he can pull his punch back, the farther that he can send his next punch out, the more power that his punch can generate. Of course a full "compress" take extra time. But we are talking about "single punch power" and not "chain punch speed".
The specific video regarding the rice bag was simply to teach the principle of relaxation of the punch and how it relates to being able to do the Chain punching. Some teachers are like that, they demonstrate principles in parts.
If you look when he is punching the bags when held, when chain punching it is definitely the "straight punch". On the "big bag" he is too close to get full extension but the principles are still adhered to. In Siu Lim Tao you bring the fist across to the heart and then push out to learn the principle. In practice you simply aim to have your fist, at impact, to be centered on your structure. He does this in the punches on the held bags at the beginning of the video.
As for your last point, I would definitely agree when the punching technique involves "throwing" your weight behind a punch. WC however punches under the centerline theory principle of "keeping" your weight behind the punch and maximizing potential punch frequency.
Bringing the arm further back also violates the centerline theory in terms of defense as well as being "iffy" under the concept of simultaneous attack and defense that gets pounded into your head. When you are punching it's not simply a matter of bringing back the one fist for the benefit of a another punch. The arm that is returning is supposed to be trapping or diverting one of your opponent's limbs, not only to defend yourself but to open the path, or simply maintain an opening, for the next punch.
As I said other punches with more waist rotation and/or rounded strikes can be more powerful, I will never deny that WC has its punching technique designed around a host of concepts that are rooted in the Centerline and simultaneous attack and defense theories. It's more complicated than below but I will try to sum it up as best as I can (not being an instructor myself.)
1. By using the structure and centerline theory, smaller people can still generate effective power as they are keeping their mass behind a punch, rather than throwing it.
2. As the strikes are straight from the centerline, the strikes hit quickly, the shortest distance between 2 points thing.
3. By virtue of the above, minimizing body rotation, and how far you pull back the fist, you can maximize punch frequency, which also benefits a smaller person as damage from strikes can be cumulative if striking the same area.
4. By minimizing body rotation, and the pulling back of the arm, you also keep the returning had in a position to readily protect your centerline (torso and brain) while also keeping the way open for the follow up strikes of the other fist via deflecting or traping one of the opponent's limbs.
Basically it says "okay let's maximize how hard a small person can punch by keeping the weight behind it rather than throwing it. Also, recognizing that a smaller person can only ever punch so hard, let's maximize the frequency at which they can strike so that cumulatively they do a lot of damage and, use your limbs to not only attack but to keep a wedge between your opponent that both defends and opens the path for attack"
It may be a poor description but that is the best I can
I think I am approaching the topic of the effectiveness of Wing Chun through the lens of what I've seen in a majority of videos depicting the art. That is to say, compliant demonstrations. From what I'm reading from you, I get the feeling that the WC training you do involves a good bit of resistance, sparring, and actual non-compliant application. In general, would you say your school's training methodology is similar to that of the majority of Wing Chun? If someone put a gun to your head and told you you had to fight a skilled opponent in the ring, would it look like the WC demos we see on YouTube or something else? You, yourself, mentioned that the classic WC stance isn't typically used in fighting. Why do so many demonstrations feature it? Is it the case that these schools/individuals haven't properly tested their art to know that it looks and functions differently in "real life" than in theory?
Yes, we do a fair amount of sparring, even with newer students, though with newer students we will place limits of available targets, which get broader, as you progress. This is especially true when we swap to Kali halfway through the class, even with a mask or safety glasses you don't wasn't to risk someone losing an eye lol. Is this typical? I can't speak to that. I chose my school after basically interviewing a lot of Sifus. Out of the gate my instructor was talking about Combatives. Of the other two WC schools in my area; one the Sifu is very skilled but he definitely sees WC from its perspective of Chinese Natural Medicine angle so I doubt he teaches this way (he also teaches Yang Style Tai Chi Chuan). The other school simply scared the crap out of me because the head of the school is labeled "Grand Master" on the web site and they say nothing about where or from whom the WC instructor learned WC.
Now as for how it looks a WC person will see it as WC. You will see that the structure is maintained, by structure I mean leg position, pelvis and torso position, the foot work and the arm position. You will also often see little things as well Say two fighters break apart for a moment, you will often see the WC guy swap positions because there is a concept sometimes called simply "same side/same side". Also when an incoming punch comes in at the WC guy you will often see what looks like a punch being thrown in response but it if you look closely the forearm is striking the incoming arm. That wasn't a coincidence, it was a
tan The hands, yeah they may be fists, or they may be cupped and not the classic straight open, but if you know what to look for you see WC.
