Understanding and Training External and Internal Oblique

External abdominal oblique muscle originates from the external surfaces of ribs 5-12. The attaching fibers interdigitate with those of serratus anterior and latissimus dorsi, forming a zig-zag oblique line on the lateral side of thorax. Insertion : The external oblique (L. externus, external ; obliquus, oblique.) is a broad, flat sheet of muscle on either side of the abs. It is named after its location (external to the internal oblique) and its fiber direction (oblique relative to the midline of the body). It is the prime mover in spinal rotation, and it has a significant role in spinal. Aponeurosis of the external oblique muscle of the abdomen; Insertion: Lateral lip of bicipital groove of humerus.
