Mostly Harmless
I've seen some of this, and there are some real hazards. The question being is your master qualified to teach basic throwing, wrist locks or armbars? Where did he learn them? Not a knock, and it may be that your coach has crosstrained and it qualified. But taking a seminar and working in elements outside of your style without being well grounded is potentially very shifty.KKW Taekwondo doesn't officially include any grappling. My master has added some, including basic throwing, wrist locks, armbars, etc.
