The external obliques are a pair of muscles located on the sides of the abdomen. They play a crucial role in trunk rotation and lateral flexion, allowing the body to twist and bend sideways. These muscles also help stabilize the pelvis and support the spine during movement. In addition to their role in movement, the external obliques assist in functions like breathing and posture. They work in conjunction with other core muscles, such as the rectus abdominis and internal obliques, to provide strength and stability to the torso during various physical activities.
