Heel hooks/twisting leg locks (grabbing the foot and twisting it)
Slamming (picking your partner up off the ground and throwing him hard back to the ground)
Small joint manipulation (grabbing individual fingers and toes)
I will admit I haven't read the whole thread yet, but my school allows all these. (Small joint depends on the roll) Are they really that uncommon?
Yes. Remember: we are training in a sport that includes dangerous moves, which can cause unconsciousness, broken bones, torn muscles, or sprained ligaments. The number one rule is to stay safe.
I've seen people end up needing surgery because someone cranked a heel hook in training. Catch and release is ok, controlled cranking it is sometimes ok if you know who you are rolling with, but in general it is a bad idea. Those kind of leg locks are also illegal in the gi for BJJ tournaments, so they are not in the scope of this article.
Slamming is also a bad idea for obvious reasons. It is illegal and counter-productive to good training. If that is allowed at your gym, find a new gym. You aren't training safely.
Small joint manipulation, besides being illegal, can hurt your fingers very easily. I was choking someone in judo. He grabbed just my middle finger and pulled. It was swollen for 2 months and I could not grip well with that hand. However, I still finished the choke. In general, small join manipulation like that can easily hurt your partner. You can't tap fast enough to a "finger" lock to prevent injury, but it still won't not stop the submission or move and simply makes your opponent more angry. Finger locks like that is a dick move.
I agree with you....rolling isn't about winning or losing.....obviously......while in the gym we are in training of course.....but at the same time a roll is a roll and i think that people that say "sorry man lets take a minute break im tired" is really annoying......especially when this could be motivated by a eminent tap.
Like I said in my previous post.....I think you should respect your partner you are in the roll with by tapping out if you can no longer continue.....
Ive read your posts for a few years on this forum and know you have been training a while......have you really not ran into one of these people?
and i want to reinforce......i don't roll in the gym for an ego boost from getting tap outs....or WINNING........i roll to train for competition and to get better....like most of my training partners.
I've run into them. I don't care either way, though. In fact, I usually just feel bad and give them some words of encouragement.
i've always dig my elbows into the thighs and people try it on me. Doesn't even hurt anymore
That's why you're just a cockroach.
