Physics of an armbar (help!!!)

How does this specific armbar work? It hurts like hell but I’m too stupid to realize how IT IS POSSIBLE! :icon_cry:

The elbow is placed near the groin, with nothing pushing it, but it eventually breaks.

I can perform this tech, but i still don’t know what is behind it!!!

I CALL FOR YOUR HELP, DISCIPLES OF THE GRACIES…

you bend de arm de way it no go. strechie non-strechie part. he get owie and tap. go practice.

is the question about how to do a standard arm bar? or is the question about some odd variation that is supposedly depicted in that picture? all the arm bars i’ve seen, and i’m newb so it’s not many, are very similar. pull head close with leg, squeeze knees, elbow above crotch (so you don’t crush your manparts), thumb up, hold wrist, lift up hips. the physics are pretty simple, you’re bending the elbow in the direction it’s not supposed to bend.

I CAN perform it correctly and make 'em tap.

It’s all about “reversing” the arm by locking the shoulder and pulling the wrist? I am used to perform armlocks in which I PUSH the elbow, but it’s not in this case. This armbar surely works, but I just found it strange…

:eusa_doh:

so you’re suggesting that this armbar works by pulling the arm out of the shoulder joint by the wrist? i’m confused about your question

Leverage

ok, despite my previous reply, i am confused what you are confused about. you are applying force in a direction the arm does not bend naturally, the net force of which is pushing the elbow. how can this not hurt? should i try to suggest you are causing a heart meridian liver blockage that typically works best on thursday afternoons? why then is the idea that the unnatural angle and force is painful not clicking?

  1. I am extremely stupid.

  2. I didn’t realize that it is possible to break a joint (elbow, in this case) by pulling what it connects (the shoulder controlled by the legs and the wrist grabbed with both hands) in opposed directions.

ok. easy drill. grab a stick. sit at a table. secure bottom end of stick with legs. place middle of stick on table edge so it rests against this "corner’. push the top of the stick. you broke the stick, yes? congratulations, you broke the middle without pulling the middle :slight_smile:

edit: ooooooh, now i get the question. the question is on what does the actual work during the break, the pulling down of the wrist or the pushing up of the hips, right? i’d say go with both at the same time, redundancy always helps.

by the way, i don’t know who that person in the picture is, but it seems like he doesn’t have a very tight armbar in that picture. is this assumption correct? or am i missing something?

This is going to trollshido. No one can be this dumb.

don’t mind os. he is only mad because you didn’t ask about a crucifix.

And he’s just mad because I armbarred him from said crucifix.

s’ok, i have changed one of my single-leg takedowns based on your observation. well worth being armbarred.

I’ve encounted several who do armbars who think that pulling the wrist away from the shoulder that breaks it.
In case you are not trolling…
You are not stretching the arm.You are securing the upper arm/shoulder by squeezing your legs together(done poorly in the pic) and controlling the lower arm with your hands/arms.
And you are pushing your pelvis into the elbow or just to the tricep side of it causing to to hyperextend.
The injury can vary, but the point of the bones running into each other can cause a small bone break.But they can slip passed each other without a break in which case the connections will stretch til they rip.
Connections being ligaments or tendons.

Strong machine is correct. You’re pushing the elbow with the pelvis. King of seals, where do you train?

He doesn’t.

This is what I was looking for. I don’t want no more attention here (I’m not trolling, I’m just a n00b!). I train in nort-east Italy, a small gym where you can find everything from weights to Tai Chi to Karate… and sometimes I train for nhb.

That’s all, folks.

Like everything in life, it is solved by better hip movement.

and sometimes I train for nhb.

If by “train for NHB”, you mean “Watch UFC”, I’ll buy that. Your ass does NOT train seriously or often for NHB if you need to ask how an armbar works.
