Abdominal external and internal oblique muscle
This week I began to build up the side of the abdomen. Actually there are two muscles building that shape: the abdominal internal oblique muscle and the abdominal external oblique muscle. Their fibers run perpendicular and the external oblique covers completely the internal oblique. Especially the lower part of the external oblique has quite a signiticant shape.
