Flexion is the bending of a joint or limb, typically in the direction that decreases the angle between the bones of the limb at the joint. It is a common movement in the body and is important for activities such as walking, running, and general movement. Flexion can occur at various joints in the body, including the knees, elbows, and spine. Stretching exercises that involve flexion can help improve flexibility and range of motion in the joints.
