Can't be choked???

In 7 years of Jiu Jitsu I've never come across this... but I have a student that seems like he can't be choked. He will let you sink in a full rear naked choke and you can squeeze the hell out of him and he won't fall asleep and he won't tap. Now, I don't have the best squeeze in the world but I can assure you the choke is super tight and would put anyone else out... Has this type of thing happened to anyone else??? Any theories on how he is able to it?

note: his cardio is TOP... he rides at least 30 miles on his bike and runs 7 miles almost every single day. I don't know if it's a factor but it's the only thing he does differently than everyone else

What ya got peeps???

Sweep the leg.

Obviously you are doing it wrong. Either that, or he doesn't have any carotid arteries.

The brain needs oxygen to function...period. Yes, there are people who can go without oxygen *a little* longer than others, but bottom line, we all need to breathe to stay conscious/alive. If he's not passing out while letting you sink a choke as hard as you want while he doesn't taps for an inordinate amount of time, then he's still possibly breathing, or can "hold is breath" longer than you can put on a 100% oxygen depriving squeeze on your choke. Plus you said it yourself, "I don't have the best squeeze." And if your guy can take a fully sunk Peruvian necktie or D'arce from a person with a good Peruvian or D'arce without passing out for 45-60 seconds. He's a freak of nature and I'm jealous =D.

My first answer to someone saying this would definitely be... "obviously, you're doing it wrong"... but trust me this is not the case. I have choked him and tapped him before. But it takes a ridiculously long period of time! My game is very choke oriented... Guillotines, neckties, and head and arm... This is one of those few rare cases where I think this motherfucker might have some sort of supernatural ability lol I asked him about it and he says that he "searches for the bubble"... he says somehow he can force a pocket of air that allows him to last a long time in a choke... what the fuck he's talking about I have no idea because he's not telling me too much about it... probably because if he tells me his secret he will release the secret to destroying it too haha... I don't know... But he's definitely a freak of nature

So you can choke him but not all the time... Kinda pointless thread isn't it? Lol

I'm just trying to see if there is anyone else that has the ability to survive chokes... he literally takes over two minutes to choke and finally tap and I think that's due to boredom... Of course I usually just go with a different approach. Armbars, Twister, or playing in the truck. It's just incredibly frustrating because anyone else would be tapping withing 10-15 seconds MAX...

A lot of people have the ability to survive chokes if they have a little room. If a choke is locked in correctly, I'm seeing stars and feeling my body tingle within seconds. The only reason that the guy is not tapping is because you are doing the choke without proper technique. The Rear Naked Choke is not just about the squeeze.

I do a check sometimes where I let random guys at the gym get a full sunk in rear naked choke without me resisting at all and 9/10 guys don't do it right. Then I fix whatever they were doing wrong and they choke me within a couple seconds. A lot of guys with bigger arms don't usually develop proper choke technique because their big arms usually compensate for the extra space (not saying this is you).

We have similar guy at our place and I can tell you this is perfect man to train your squeezing endurance and power. I achived a big success when playing with him to look only for chokes - triangle, RNC, gillotine, darces,etc. You can tap him but after long squeeze and even the angle is perfect you have to continiue breathing and squeezing. After 3-4 months trying everytime to catch him in such subs the time went less and less, but he is still very tough and is holding till the end.
One of the reasons for that in my opinion and experience is that there are guys like those, who have very flexible necks (and I dont mean that he can roll trhough it or stay like Ryan Hall), I mean that when you catch the choke you can squeeze it almost to the bone and there is still a place to breath. Also I found that he is hoping when someone hold the choke till the hands/legs of the attacker to burn out and after that as he is sayin:" it is easy - I can breath easily :))". Also I found that straight gillotine like Marcelo's is working much better, because its direct to the neck and obviously he is very flexibile on the sides , but not in front! Also that kind of guys are helping you to work even more for the angles of the chokes, so use it.(as Jay said - its not just about the squeeze). Every time I tap him I am asking if I was doing a choke, or something else ( for example neck- crank). That is helping you to understand the details of the technique you are using in that moment, so just ask him what,where he felt something.
