WHATS INVOLVED IN A STRAINED ABDOMINAL MUSCLE?
Colon pulled his external oblique muscle. The two external abdominal oblique muscles lie on the sides and front of the abdomen and are the largest of the muscles in this area. These flat muscles are attached to the ribs and the pelvis in such a way that both muscles, acting together, bend the spine forward. One side acting alone can bend the vertebral column sideways and rotate it, bringing the shoulder of that side forward.
