What action is performed during lateral flexion of the spine?

Lateral flexion of the spine specifically refers to the movement of bending the spine to the side. This action involves the lateral (side) muscles of the torso, particularly the obliques and the quadratus lumborum, which facilitate the movement and stabilization of the spine during this action. When you engage in lateral flexion, you tilt your body sideways, bringing the shoulder closer to the hip on the same side. This is an important movement in various activities and exercises, as it helps improve flexibility and strength in the core.

The other movements mentioned in the choices involve different motions of the spine. Bending the spine forward refers to flexion, while bending it backward refers to extension. Rotating the spine involves twisting, which is a distinct motion from lateral flexion. Understanding these movements is crucial for effective exercise programming and ensuring proper form during workouts.
