Arm wrestling is a sport with two participants. Each participant places one arm (either the right or left, but both must be the same) 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^{[citation needed]}. It is sometimes used to prove who is stronger between two or more people. In competitive arm wrestling, as sanctioned by the United States Armwrestling Federation (USAF), arm wrestling is performed with both competitors standing up with their arms placed on a tournament arm wrestling table^{[citation needed]}. Arm wrestling tournaments are also divided into weight classes as well as left and right-handed divisions. Furthermore, strict rules such as fouls given to penalties (such as the competitor's elbow leaving a matted area where the elbow is to remain at all times, or a false start), and trying to escape a possible arm pin by breaking the grip with the opponent may result in a loss at the table^{[citation needed]}. Paraphrasing USAF rules, arm wrestlers must straighten their wrists without a time lapse of one minute during competition.

John Brzenk (born July 15, 1964) is a professional armwrestler from the United States. He competes in the Professional Armwrestling League, and as of 2009 is the number-one armwrestler in the world. John was named by the Guinness Book of World Records as the "Greatest Armwrestler of All Time"

John Brzenk's father was an arm wrestler and John says he gained some of his forearm size through genetics. He arm wrestled across tables in school for about five years. When he was in eighth grade, he broke his arm while armwrestling a friend of his father. When he was 16 years old he participated in his first tournament.

John Brzenk won his first world title on ABC's 1983 Wide World of Sports when he was 18 years old. His right forearm is 16 inches in circumference, and his left is 13.5 inches. The heaviest opponent he faced weighed 660 lbs, whom he defeated. John has lost a supermatch only once, and only a handful of people have beaten him (including his brother, Bill). The most noted of them are Devon Larratt and Alexey Voyevoda. Aside from arm wrestling, he works as a mechanic at Delta Air Lines. He says the job is non-physical so his arms get plenty of rest. He makes $13,000 to $15,000 a year arm wrestling.

Paul Michael Levesque (born July 27, 1969) is an American professional wrestler, wrestling executive, and actor better known by his ring name Triple H, an abbreviation of the ring name, Hunter Hearst Helmsley. Currently, Levesque works in the front office of WWE as the Executive Vice President of Talent and Live Events, and as Triple H appears on television as the (storyline) Chief Operating Officer, and part-time wrestler.

Levesque began his wrestling career in the International Wrestling Federation as Terra Ryzing before joining World Championship Wrestling (WCW) in 1994. After briefly using the Ryzing name, he changed his character to Jean-Paul Lévesque, a French-Canadian aristocrat which would be similar to his character Hunter Hearst Helmsley, that he used in his early years with the World Wrestling Federation (WWF) from 1995 onward. He later abbreviated his name to Triple H and adopted an alternative image in the D-Generation X (DX) stable. After the dissolution of DX, Triple H was pushed as a main event wrestler, winning several singles championships. As part of a storyline Triple H married Stephanie McMahon, who later became his real-life spouse. In 2003, Triple H formed another stable known as Evolution, and reformed DX with Shawn Michaels in 2006 and 2009. He is heavily involved in the writing process of WWE programming, and holds complete creative control over his television character's storylines, win/loss record, and championship reigns.
