When you learn to box, everyone learns the SAME movement/actions, the same fundamentals, e.g., the jab, cross, hook, slipping, etc. But you don't "learn to box", to put these things together for yourself, and develop into a fighter, except by and through boxing (sparring in the ring). It's not through your boxing teacher but through your sparring partners that you "learn to box". It's the same with BJJ, and the same with WCK.
Yes, it is. Fighting and its methods, whether boxing, wrestling, BJJ, or WCK, is an INDIVIDUAL endeavor. When you see people box, do you see the same movements -- jabs, crosses, hooks, slipping, etc.? Yes, because you see
the same fundamentals in action. Boxing is boxing. And that's why we can look at any individual in a fight and see whether or not they are using boxing -- just by looking at their movement: are they using boxing movements (boxing fundamentals)?
Similarly, WCK is WCK. Every *legitimate* branch/lineage has the same fundamentals (YJKYM, jik chung choi, tan sao, fook sao, bong sao, etc.). However, how an individual uses/puts together those fundamentals and/or how various groups emphasize those fundamentals can and will vary.
Results are the only true influence. When you box (spar) you find what works best for you, and you put together your own game using the fundamentals.
I didn't learn it with the weighted jacket either (which makes no sense IMO).
I'm not talking about "a similar movement" -- I'm talking about the same fundamental skills.
Love your movies.
