I was a co-founder of CFAR in 2012, same year I got my PhD in math education & left academia. I’d been actively trying to save the world for about a decade at that point. I left CFAR in 2018 due to strong disagreements in approach. I then spent several years focused on a “hippie arc” (meditation, yoga, plant medicine ceremonies, etc.) and “de-mystified” in summer 2024.

Boy do I relate. For whatever reason, the demos on YouTube are almost universally weirdly bad. I’m guessing Ivan found the one he linked to because I linked to it; it’s the clearest short demo I’d found.
I’ll see about making one sometime. It’s a little tricky for me in particular to convey over video because I’m so visibly strong. But I’ll give it some thought. Maybe I can ask for help from some of the bodybuilders at one of the local gyms.
Sadly I can’t draw a force diagram because I honestly don’t know how it works. I can almost make sense of it. The technique works perfectly well if I put my wrist on an unyielding inanimate object like a table, so I think I’m somehow transferring the downward force near the elbow into the upward force on the wrist. But I’m not at all sure how that “somehow” works. I just… do it. By “extending ki”. :-P
This one is just awful. Just utterly dumb. It’s correct that losing focus when you’re learning the technique causes it to fail. But at no point in the video does he demonstrate the actual thing. They’re treating it like mysterious magic — which makes sense! It’s hard to do without treating it like a bit of magic at first.
I can do the unbendable arm while distracted now. It’s something my body just does when I choose for it to.
Yeah, I’m with you, this isn’t impressive. It’s kind of sort of right ish. But his understanding of how to do it is sloppy IMO. That slop shows up in how he stumbles around.
Complete relaxation is not necessary for doing this technique. But if you’re doing the technique right, tremendous relaxation is possible. So if you want to check if you’re doing it right, you can try relaxing more than you would be relaxed if you were fighting to keep your arm straight.
He’s right that the arm might bend a little. It’s an adjustment thing. Kind of like how your knees might bend a little if you catch a falling heavy object: it’s just a spring action as your body adjusts to the new incoming force. But if you’re doing unbendable arm right, you can actually let the arm completely fold up and then straighten it out again while they’re applying force. It’s quite easy.
But my guess is that he’s not referring to adjustment. I think he’s making excuses for poor technique.
At a glance, it looks to me like this guy really is doing the thing I’m talking about. There might be extra stuff going on, but my impression is that if you vary that extra stuff it won’t affect the power of the unbendable arm. I really don’t think it’s a matter of “advantageous position”.
I’m not going to die on the hill of “This guy is authentic.” It’s just a passing impression from watching the video. That said, I might start linking to this demo instead honestly! :-D Although I do like the original guy’s looseness better.
I’d be happy to do this demo with you with the “advantageous positioning” mostly however you want it to be. I say “mostly” because there are some things that’ll break the technique’s ability to work, and I can nearly always tell you ahead of time what those will be. (E.g., if you rigidly pin my upper arm to a stationary object like a countertop, the technique won’t work.) But it’s really not about the level of advantage I think you’re talking about. I can do the unbendable arm on my knees with my arm pointing straight over my head. I can do it with two people, one pushing up on my wrist and the other pushing down on my elbow. I hold totally inanimate objects using this technique, like sacks of groceries, by placing a wrist on a surface like a wall or a railing. I’m pretty darn sure it’s a physics trick having to do with redirecting forces somehow. It’s just a little tricky to learn how to do it.
I’m very, very confident it doesn’t work via moving goalposts.
I don’t know how to delineate all the “rules”. If you change the context such that you’re not testing the arm’s unbendability, then you won’t get to experience the thing I’m talking about. There are some ways of testing unbendability that will, in fact, get even my arm to bend in defiance of my trying to use this technique. There’s an amount of force that should, in theory, cause tendons/ligaments/bones to start snapping, at which point of course the arm will fold.
Maybe there are other things for me to name there. I don’t know.
But if you’re concerned about any hidden rules here, feel free to ask me about them. If you give me a scenario, I can tell you whether (a) it’s testing the thing I’m talking about and (b) how it’d do.
E.g., if you vice grip my upper arm and use a car jack against my wrist to force my arm to bend, it absolutely will. I have no power against that setup.
E.g., if you stare really hard at my arm to try to get it to bend but you don’t touch it, you won’t be testing the thing I’m talking about.
E.g., if you are trying to bend my arm like in many of these demos but you surprise me by smashing my foot really hard, I might stop doing the technique and you might successfully bend my arm — not because it failed but because I stopped doing it. (Although even here, if it were somehow really dire that I demo it, I might flinch and it might falter for a moment, but I’d be able to recover it and re-extend my arm against your force.)
And as I said up above, within some sensible limits I’m very happy to demo this technique in person. I’d ask that you not smash my foot or otherwise be mean about it! And there are some tests you might want to do that I can just flat-out tell you would cause the technique to stop working, so I don’t think there’s much point in running those. But if you want me to, say, do it blindfolded while lying on the ground and singing the national anthem, I’d be totally happy to do that. It’ll work just fine.
