The word brawn is from the Old French word braon, which means “fleshy or muscular part,” referring to a part of an animal that people cook and eat. British English still uses brawn to mean meat, headcheese in particular. In American English, brawn refers to strength and heft. You may also have heard the adjective brawny, meaning strong and muscular.

"brawn" はbrainsに対する、体力の内の筋力を示しているのですね。
