I ask cause sensitivity training is found in all grappling arts and only one striking art, Wing Chun.

If that’s the case that’s probably why some people feel Wing Chun is useless. They don’t understand the grappling aspect.

It may also be why trapping is misunderstood. In essence it is stand up grappling, which would make Wing Chun a striking and grappling art or “MMA”. My opinion.

Comment/Answer: That’s a very interesting point, and valid. I’ve heard similar comments before.

Personally, I would not call it a grappling art. There is no traditional school that I’m aware of that specifically teaches their students to go to the ground.

Where I train, we learn “anti”-grappling defenses. But this is not grappling by any stretch of the imagination. It’s a series of strategies to avoid getting taken down and to attack a grappler at his vulnerable points.

There are many schools that have added grappling to their curriculum. This is new and a result of modern times. I believe in many cases it’s a marketing plan to attract a wider range of potential students who are fans of MMA (UFC).

Perhaps in 300 years, Wing Chun will be tightly integrated with street applicable grappling techniques, much like legend tells us what happened with the Dragon Pole and Wing Chun.

I recently came across and reviewed a resource that shows how to use grappling in a real-life street scenario.

I thought it was pretty good because while most grappling resources focus on competition, this book and DVD combo shows you how to use debilitating strikes from the ground, and how to take on knife attacks and multiple attackers while in the gravel.

Another tool that can help you improve your ground game is this video training guide that speeds the grappling learning process. Pretty cool.

Thanks for your question!
