I've been seeing some discussions elsewhere about applications for gedan barrai, lately, and decided to record and share one that I like using in conjunction with a tsuki of some kind--a very common combination of techniques across a wide variety of styles and kata. Of course, you could replace the shotei-tsuki I used with any other strike you prefer that fits the situation.
The attack this deals with is a grab to the upper arm that is used to control the limb and pull the victim to another location--according to the last UK crime study I saw, this was the #1 attack against women, but it's possible this has changed. In the video, I used someone smaller than me because he was the only uke available at the time, but I have confirmed that it works quite well against larger, stronger people. I know that my video isn't as clear and detailed as many, but I hope you can see the gist of what I'm trying to show. Thanks!
