What does flexion refer to in the context of joint movement?

In the context of joint movement, flexion specifically refers to the bending of a joint, which results in a decrease in the angle between the bones that form the joint. For example, when you bend your elbow or knee, you are performing flexion. This movement allows for greater mobility and is integral in many everyday activities, as well as in various forms of exercise. Understanding flexion is crucial for fitness instructors because it plays a significant role in designing exercise programs that enhance flexibility and strength while preventing injuries. Knowing how joint movements like flexion work helps trainers to instruct clients on proper technique and body mechanics.
