Leave already. Do it. Joint injuries are NOT something to mess with. I don't know about you but I'd freaking kill someone if they caused me a lasting injury.
As far as I'm concerned if a joint lock is deliberately held after a tap, it becomes assault. I'm pretty sure a magistrate would see it that way too.
I sent my missus to Kenpo and they did push her past her comfort zone (as any good MA would do). But this sounds like the guy applying the hold is showing off by knowingly inflicting pain on you. Good thing you're leaving as there are better instructors out there. Good luck on your journey.
tell him you want to leave because he is a total douchebag and you like having the full use of your limbs.
Follow the advice below as previously posted... That school sounds like your typical garbage dojo anyway. Read the McDojo sticky on here or on Bullshido.com
Worth also noting that repeated hyper extention of joints is bad for them. So even if he isn't causing obvious injuries he may be weakening your joints, pain is there for a reason, its a warning.
I have seen similar instructors in the past. These guys got off on dominating students in front of the class, at the time we thought this was "the traditional way"... it was not the traditional way. Time passed and we saw it was just a bully with ego problems. Your instructor is ignoring your life line, it's a serious personal mis-conduct for him to ignore your tap, he can ingore grunts, yelps and hisses of pain but NOT the sign that says "Stop I think your going to injure me" I'd speak to your instructor, if he does not immiediatly rectify.... ...Leave. People like that have very little worth teaching.
Please leave already. I am getting angry just thinking about what might happen to my weak shoulder if someone kimura'd me and didn't stop after I tapped. I would go to the police for sure. As Holyhead said, after the tap, not letting go is assault.
Its a hard 1 to call. either your instructor is a bully or you were expecting a pillow fight and not a martial arts class.
Nonsense. It's a demonstration in class not a MMA fight. He has no business harming people like that.
i think he meant training is not a fight, in training your goal should always include yours partners safety, in competition its up to the other fighter and the ref to look after my opponent im there to win, so a different mind set, I dont let go or stop until the ref says so and sees the tap But i think everyone on this thread is in agreement the poster should look elsewhere for training lol
Let's just hope your instructor doesn't learn this [ame="http://www.youtube.com/watch?v=oU9CjBIxD8U&playnext=1&list=PL76CD074C54544C98"]YouTube - Tony Cecchine's American Catch Wrestling: Hooks vs. Submission Holds (top wrist lock / "key lock")[/ame]
Nope...just really in-depth breakdown of an americana/keylock/top wrist lock from side control. Lots of little pointers from a non-BJJ perspective.
or alternatively its rubbish talk about the difference between a sub and a hook ( ) from someone who never competed because of a bad back...., made up his golden gloves credentials and ripped a load of people off.....
