It is great that you display the progress of your Wing Chun boxing and by doing so I assume you dont mind some feedback.
---Good feedback is welcome! Harsh judgmental criticism not so much.
1. You remove the flow of the bong-lop da drill and treat it as a "I move and you wait" kind of drill.
---You are right. My student doesn't have this drill down well at all yet. I probably should have waited until he could do it smoothly with me. But I've just started showing this to them. I'll probably swap this video out with a better one later on when we can make it look sharper.
To me the force pushing the hand of the opponent is what gives that spring force causing you to receive an attack back when letting go. Sensitivity in the drill, I do not see any of that in this drill. Which is perfectly fine, but it is a remark to better understand my feedback and reject it if my base differs too much to yours.
---No, point taken! We were definitely loosing some of the continuity of the drill by not maintaining good contact. That will get better as my guys learn it.
2. Now this is where I have more of an objection. You make too many moves on your "opponent" with that final punch in the stomach. The way the drill is demonstrated you make a drill where you do bong-lop da... follow up with a punch in the stomach against a frozen opponent and then perhaps also stepping. Not sure I like the whole idea of a non-resisting opponent unless the intent is just to simply train the punch itself without any real application theory to it.
---That's an interesting comment, given how elaborate many Wing Chun lineages get with this drill! I thought what we did was pretty simple and straight-forward in comparison!

But it isn't too many moves. The idea is that the Bong & Lop with the backhand motion sets him up. If he doesn't respond he gets hit in the face. But when he puts his hand up to stop the strike he leaves an opening and gets hit in the solar plexus instead. It's quick and not complicated it all. If flows nicely just like any boxing combination. He is resisting when he throws the hand up to stop the punch. And notice that we are actually close enough that all of those strikes can land! This is unlike how this drill is done in a lot of Ip Man lineages where you are standing back from the partner and neither one of you are actually within real striking range.
3. You opponent is learning to have two hands in contact with one of yours. Instead of the opponent being aggressive and having is intent on attacking you it seems he is focued on your arm instead. This is noticed when you punch in stomach. What are his hands doing there? Is that the actually response you want people to learn as a reflex?
----I see what you are saying. The way we are doing the drill, he isn't really reinforcing a good response to the Bong-Lop Da. He is just falling right into to the trap the drill is meant to create. So I guess you could say we are using the drill to really commit actions of the guy doing the Bong-Lop and strike to muscle memory but not so much the defender's actions. But if you think about it, we are doing 2 steps in our basic drill. Most Wing Chun people only do 1.....Bong & Lop and partner stops your punch....1 step. We could do that as well by leaving out the punch to the solar plexus. I guess I skipped a step in showing the drill and should have done the even more basic 1 step drill first....like most people do.
4. Elbow down, not to the side. It seems you are intentionally opening up that stomach for an attack.
----Even with the elbow down there is going to be a gap that is easy enough to punch through. And besides, we train with the idea that if we ever use this....it won't be against a trained Wing Chun guy that is good at keep his elbows down and holding centerline.
So feel free to argue or ignore this message. I just feel any uploaded video deserves honest feedback.
---No, thanks for the feedback! Good things to think about!
Just a final question, you want to integrate boxing techniques for long range fighting game. Why even bother doing modified chi-sau drills with boxing techniques. It is not at all what has made boxers so great at long range. I am just worried that you seem to remove the aspect of Wing Chun and yet trying to maintain some training to create a close range boxer rather than adding a long range game using boxing techniques to a close range defined Wing Chun style.
----Well, like I explained in my intro video on the page, and I think higher up in this thread....there is a spectrum. On one end someone could do "classical" Wing Chun unchanged when in close, and only do Boxing things at long range as you say. I think Mark Phillips is a fairly good example of that. On the other end of the spectrum you can basically have boxing, but add in Wing Chun "hands" when in close to expand defensive abilities as well as working some Chi Sau skills from some of the drills. I think Paul Rackemann is a good example of this. I'm trying to be more in the middle....a good hybrid of both Wing Chun and Boxing. So I'm still using most of the Wing Chun drills and still doing the Wing Chun forms. But I've changed the mechanics to use the boxing "engine". So I'm sure it will be a trade off. This will make some of the Boxing better and some worse and likewise some of the Wing Chun better and some worse. But its all fun!
