flexes

Flexes is the plural form of flex in several contexts. In anatomy and physiology, a flex is a movement that bends a joint, reducing the angle between two body parts. Flexion is produced by flexor muscles, while the opposite movement is extension. Common examples include elbow flexion (bending the arm), knee flexion (bending the leg), and wrist or finger flexion (curling the digits). In medical settings, flexion is often described relative to a specific joint and measured to assess range of motion.

In everyday language, to flex means to display strength, wealth, or status, sometimes in a deliberate or ostentatious way. "Flexing" refers to this act of showing off, whether through physical prowess, purchases, or social media posts. The term has become popular in popular culture and online discourse.

In engineering and materials science, the verb flex can describe bending under load, and related terms such as flexure refer to the deformation that results from such bending. Components designed to flex, such as hinges, flexible joints, or compliant mechanisms, allow controlled bending in a device or structure. While these uses are more technical, they share the core idea of movement or deformation through bending, which is also summarized by the broader concept of flexing.

Overall, flexes can denote a specific bodily movement, a social display, or a mechanical bending action, depending on the domain.
