WC, from its beginning, was developed to fight against other styles of fighting. Initially this was probably restricted to hung ga, long fist systems and the like.
Now fast forward a century or two.
In order for WC to stay true to the spirit of its origins, we need to continue....or for some of us, maybe even resurrect this tradition.
Pressure test. If someone in your WC group has previous MA experience, pick his brain , work with him every chance you get....use him for the valuable resource he is.
If you don't have anyone in your group that fits that description, then go out and find someone. Find a buddy who likes to wrestle or box or kick and glove up and pressure test.
Don't just practice Martial incest. ....not a pretty sight.
