Arm wrestling is a sport with two participants. Each participant places one arm, both put either the right or left, on a surface, with their elbows bent and touching the surface, and they grip each other's hand.
The goal is to pin the other's arm onto the surface, with the winner's arm over the loser's arm.
Various factors can play a part in one's success in arm wrestling.
Technique and overall arm strength are the two greatest contributing factors to winning an arm wrestling match.
Other factors such as the length of an arm wrestler's arm, his/her muscle and arm mass/density, hand grip size, wrist endurance and flexibility, reaction time, as well as countless other traits, can add to the advantages of one arm wrestler over another. It is sometimes used to prove who is stronger between two or more people.
