Arm wrestling is a sport that has been practiced for hundreds of years. It is a competition between two players to determine which is the stronger of the two. For this, two players sit around a table and each put one elbow on the table. They hold hands and have to push the hand of the other player in order to make it touch the table, whithout ever raising their elbow.
Whoever manages this wins a point.
One of the most famous players is undoubtedly John Brzenk.
