From Wikipedia, the free encyclopedia. The external oblique muscle (of the abdomen) (also external abdominal oblique muscle) is the largest and the most superficial (outermost) of the three flat muscles of the lateral anterior abdomen.
The oblique muscles wrap around the sides of your trunk in a circular pattern. There are two oblique layers: an external and an internal layer. The external layer is located directly under your skin; this is followed by the internal layer and then by a layer called the transverse abdominus.
