All of you who are more the "one, two, three, four, I declare a thumb war" type: Take a seat.

Hundreds of arm wrestlers will compete at Gilley's in Dallas on Saturday, May 14 for the World Armwrestling League's 2016 Southern Regional Championship. Everyone who competes had to qualify at an earlier round, though anyone is allowed to spectate for free.

You may think arm wrestling is a loud, boisterous exercise, but much of it takes quiet concentration. Take a look at champion Devon Larratt, on the right, arm-wrestle "Thor" Björnsson, a.k.a. "The Mountain" on Game of Thrones.

Spoiler alert: The Mountain lost. Even though he's twice Larratt's size.

This year's competitors, both men and women, are "soldiers, firefighters, bankers, engineers, teachers and stay-at-home parents," says League chief operating officer Ben Murray. Most are "professional pullers" -- the term for armwrestlers who regularly compete -- though there's also an amateur division.

About $62,000 is up for grabs for the winners in Dallas. Victors then compete in Las Vegas at the championships this summer, which air on ESPN. There's as much as $144,000 in prize money available to winners in Vegas.

"Arm-wrestling is about more than big biceps, although that helps," says a statement from the League.

Many of the competitors have "hilariously awesome hand strength," says the League. Check out this guy who can roll a metal frying pan:
