i was wondering, exactly which muscles are most important for arm-wrestling?

from the movement, i'm guessing it's a split between triceps and biceps, and also a little bit forearm? what do u guys think?

nobody knows?

Mostly forearm, then biceps, then your hand muscles

hand muscles? didn't know they existed...what exercises are there to work out these muscles?

Hey dude.. its mostly your forearms and wrists...

Bro, It all technique and some forearm!

Its your whole upper body. It all plays a role.

If you want to work your grip go to ironmind.com and buy a captain of crush thingy. They are awsome , and kill your hand. They improve your grip so well if you work with them it is insane. Just make sure you take time off so your hand can rebuild. I love the things and they are very addictive.
