Today's video contains some bad language, so once again, if you have kids or impressionable minds around, best you err on the side of caution.
It comes, once again, courtesy of the AIM Academy in Melbourne (see Resources section) and features RAW Combatives chief instructor, Jim Armstrong. While we do differ in choice of technique in that we advise against closed fist punching for those without high degrees of training, Jim's core message about "flicking the switch" and making a decision to attack is key to all effective self defence. And he phrases it in a way that only a Geordie can. :)
