So what is the problem? If you listened to what Clear explained the training drill makes sense. The Bagua I have seen was totally explosive as taught by Erle Montaigue but soft training is still part of it. This video has nothing to do with stopping a grappler.I found a few more vids from the author in the article;
Did you know you can stop a grappler by walking around in a circle and pushing the big meanie-head away with your palms?
Yeah, me neither.
