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.

Arm wrestling puts enormous torque/twist on the upper arm’s humerus bone to a degree seen in few other physical activities. Most people’s bones are not accustomed to being significantly stressed in this direction, and injuries can occur surprisingly easily. The arm typically fails because of a diagonal break at or below the midpoint between the shoulder and the elbow.
The natural tendency of an inexperienced arm wrestler is to push the hand, wrist, and shoulder in the same coordinated direction, against the force being applied by the opponent.[citation needed] This is how we throw a baseball or hit a tennis ball.
However, turning one’s shoulder this way simply adds to the torque already being applied to the humerus by the opponent. US Arm Sports advises of the danger of “letting your shoulder get inside your hand.” It is better to pivot your shoulders so that you never look away from your hand.
