external abdominal oblique
compresses abdomen
The external abdominal oblique is a flat muscle located in the abdominal area. It is the largest and most superficial of the abdominal muscles. This muscle runs diagonally, from the lower ribs to the pubic bone and the iliac crest.
The external abdominal oblique plays an important role in core stabilization, lateral flexion, and rotation of the trunk. When this muscle contracts unilaterally, it rotates the trunk to the opposite side. When it contracts bilaterally, it flexes the trunk forward.
The external abdominal oblique is commonly targeted in core strengthening exercises such as side planks, Russian twists, and bicycle crunches. Strengthening this muscle helps improve posture, stability, and overall abdominal strength. It also contributes to improved athletic performance in activities that require rotational or lateral movements, such as golfing or tennis playing.
