Were I a younger man and relatively fit and healthy, this is something I would be interested in doing. There is a Knights Hall in Nashua, NH, a gym decked out for medieval martial arts, including armored combat, and they call their workouts KnightFit.
Their sport, armored medieval combat, is no Renaissance fair, live-action role play. It also puts to lie the battles one sees on “Game of Thrones” and the “Lord of the Rings” movies, in which lithesome swordsmen twirl their weapons like batons, dancing and slashing with choreographed precision as they cut apart less-skilled opponents and dodge the strikes of more accomplished foes.
The weapons the combatants of The Knights Hall wield are real, carefully crafted to replicate the arming swords, axes, dussacks, falchions and faussarts wielded by knights of the late Middle Ages. Though dulled to prevent bloodshed, the swords and axes can lop off unprotected limbs if swung with enough force, and produce sparks when they strike cold steel.
