Morphology

flex + one + muscle

The expression pairs 'flex' (to contract or display a muscle) with 'muscle' used metaphorically as strength or power, so the idea of 'showing strength' is partly inferable from the constituents. However, the pragmatic sense of demonstrating power or making a warning is an extended metaphorical use rather than a strictly literal composition, so a B1 learner who only knows the words may not fully predict the speaker-intent without exposure.

Etymology

Flex one's muscle comes from the simple picture of someone flexing a muscle by bending the arm to show strength. So it means 'to show power or strength' to impress or warn others.
