ACTIONS:

• The external abdominal oblique flexes, laterally flexes, and contralaterally rotates the trunk at the spinal joints.
• It also posteriorly tilts and ipsilaterally rotates the pelvis and elevates the same-side pelvis at the lumbosacral joint.
• The external abdominal oblique also compresses the abdominal contents.
