Brute strength is a term used to describe physical strength or power that is achieved through natural means, such as BRAWN, MUSCLE, and rawpower. BRAWN is the physical strength of a person, usually referring to their muscles. MUSCLE is the tissue in the body that contracts to produce movement. Rawpower is the ability to exert force without any additional help or support. All three of these terms are related to brute strength, which is the ability to use physical strength to accomplish tasks.
