Does anyone have a clear definition of the difference between "internal" and "external" when it comes to martial arts? This seems to have become a "buzzword" in recent years in Wing Chun circles. There are often entire discussion on the FB forum about whether someone's Wing Chun is "internal" or not. A couple of the decades ago the buzzwords were "hard vs. soft." From the way I have seen people describing "internal" and "external" though, it doesn't really equate to the same thing. Just curious if anyone has a good clear explanation to share.
