Ion Oncescu wins 1,024 arm-wrestling matches in 24 hours

Ion Oncescu turned Sun Plaza Shopping Center in Bucharest into an all-day gauntlet on February 12, 2012, winning 1,024 arm-wrestling matches in 24 hours and never losing a pull. Guinness World Records says the record was built on multiple challengers, with a €1,000 prize dangled for anyone who could beat him, and Oncescu beat every opponent that stepped up.

The scale of that effort is what makes the number land. One account says the match marathon was televised live on Sport.ro and lasted almost eight hours against about 1,000 opponents, which pushes the feat beyond a niche stunt and into full public spectacle. This was not a lone exhibition bout. It was a conveyor belt of fresh arms, one after another, with Oncescu holding up long enough to win every completed match before the finishing signal.

Thirteen years later, Matthias Schlitte raised the bar again. Guinness lists the German professional arm wrestler at 1,064 wins in 24 hours, set in Munich on August 29-30, 2025, on the set of Die große Show der Weltrekorde and livestreamed overnight on Joyn. Schlitte, known as “Hellboy,” was born with a congenital condition that left one arm larger than the other, a reminder that arm wrestling’s stars are often defined as much by anatomy and adaptation as by brute force. His record changed the measuring stick from simply surviving the line to surviving it longer than anyone else.

The sport’s biggest crowd record points in a different direction: 1,450 people arm wrestling simultaneously in Lahore, Pakistan, on March 13, 2013. Guinness says the participants were university students from Lahore and that the mass arm-wrestle lasted five minutes, with a Guinness judge traveling to the Punjab Youth Festival to verify it. That is the clearest proof that arm wrestling scales both ways, from one athlete grinding through a marathon to thousands of hands locked at once.

The institutional backdrop matters too. The World Armwrestling Federation was founded in 1977, and its first world championship followed in Wetaskiwin, Alberta, in 1979. Put those dates next to the record book, and the picture sharpens: arm wrestling is not just a bar-room curiosity, but a global participation sport that can fill a broadcast slot, pack a festival floor, and still reduce everything to two hands and a finish signal.
