muscle

Do you have the muscle to muscle your way to the top? Muscle is both a noun and verb associated with strength, power, or the use of physical force.

In addition to biological muscle, like the biceps in your arms, muscle can refer simply to power or authority, as in “We have the muscle to get the job done.” Muscle can also refer to a hired thug. In a similar sense, muscle is used as a verb to mean “use force.” A bully might muscle someone out of their lunch money, or you might muscle your way through a crowd by pushing people out of your way.
