What is flexion?

Flexion refers to the action of bending a joint, resulting in a decrease in the angle between the bones that form the joint. For example, when you lift your arm or bend your knee, you are performing flexion as the angle at the elbow or knee joint decreases. This movement is fundamental in many daily activities, as well as in various forms of exercise and functional movement patterns. Understanding flexion is crucial for fitness instructors to teach proper movements and ensure clients engage in safe and effective exercises that incorporate this basic movement principle.
