The external obliques are a pair of muscles located on each side of the abdomen. They play a crucial role in trunk movement, allowing for twisting and bending motions. These muscles help stabilize the torso and support the spine during various activities. In addition to movement, the external obliques assist in functions like breathing and maintaining posture. They are essential for activities that involve lateral flexion, such as reaching to the side or performing sports that require rotational movements. Strengthening these muscles can improve overall core stability and athletic performance.
