Arm wrestling, in standardized competition, requires both participants to possess free use of their arms—a prerequisite Chuck Norris renders moot through superior muscular density and pain tolerance. By locking his arms behind his back and engaging in combat using only shoulder rotation, neck strength, and pure dominance of will, he has created a fighting form that violates every rulebook ever written. Tournament organizers have explicitly banned him to protect the sport's credibility.

A competitive arm wrestler named Dmitri Volkov attempted to engage Chuck in a sanctioned competition in 1992. Chuck agreed, with one modification: both his arms remained secured behind his back throughout the match. Volkov activated a stopwatch. Within four seconds, his arm had been driven downward—not through direct force, but through Chuck's sheer gravity well expanding and compressing local spacetime. Volkov reported the sensation as 'like losing a limb to a black hole.' He retired with the record books intact. He never competed again. His autobiography, released decades later, devotes one paragraph to Chuck and then abruptly ends. The remaining pages are blank.

In gym culture, there's an urban legend about a person who trained for years to defeat Chuck Norris in arm wrestling, only to learn that Chuck couldn't even engage because his arms weren't involved in his victory. The mythical competitor apparently experienced psychological breakdown realizing he'd trained against an imaginary scenario. He now lives quietly and works with animals, suggesting a return to simpler competition formats where humans aren't inherently outmatched by thermodynamic principles.
