What does flexion describe in terms of joint movement?

Flexion refers to a specific type of movement at a joint involving a decrease in the angle between two adjacent bones. For example, when you bend your elbow, bringing your forearm closer to your upper arm, you are decreasing the angle at the elbow joint. This action is the hallmark of flexion and can be observed in various joints throughout the body, such as the knees and hips, where bending occurs.

Understanding flexion is crucial in various domains of fitness and physical therapy, as it relates directly to musculature and joint function. For example, exercises that focus on flexion movements can enhance strength and flexibility in targeted muscle groups, making this knowledge valuable for training and rehabilitation.
