Dr. Armond H. Seidler of the University of New Mexico invented the Pugil Stick training method during World War II.

Military procedures for pugil bouts are often detailed, with United States Army and United States Marine Corps both prohibiting pugil training by anyone who has recently suffered concussion of the brain, lest they suffer traumatic brain injury, or had a tooth extraction within the past 24 hours.

The concept of the military pugil stick bout was adopted by the producers of the American television game show American Gladiators, who used it to create one of the physical events for the series called Joust (no relation to jousting); the object was for competitiors to use the sticks to knock the opponent off of a platform.

The name "pugil stick" is a neologism from the Latin noun pugnus (fist), the source for other English words such as "pugilist" (boxer) and "pugnacious" (eager to fight).
