 Abdominal Training
The key abdominal muscles for low-back health may be the internal obliques, as opposed to the rectus abdominis (Plowman, 1992).
Both the external and internal oblique muscles are involved in flexing the rib cage and the pelvic bones together, sideward bending (lateral flexing) of the trunk, and rotating the trunk.
The mid-section muscles consist of the rectus abdominis and the internal and external obliques.

 eMedicine - Abdominal Wall Reconstruction : Article by Bradon J Wilhelmi, MD
Other abdominal wall structures located lateral to the rectus abdominus muscles are the external oblique fascia and muscle, internal oblique fascia and muscle, and transverses muscle and transversalis fascia.
Lateral traction of the external oblique, internal oblique, transversus, and rectus muscles places tension on the fascia at the linea alba and on the skin to increase risk of skin and fascial dehiscence.
The linea alba is the fusion of the anterior and posterior rectus fascia, which is located in the abdominal midline between the rectus muscles from the xiphoid to the pubis.

 eMedicine - Abdominal Wall Reconstruction : Article by Bradon J Wilhelmi, MD
Other abdominal wall structures located lateral to the rectus abdominus muscles are the external oblique fascia and muscle, internal oblique fascia and muscle, and transverses muscle and transversalis fascia.
Relevant Anatomy: In addition to skin and fat, the abdominal wall comprises several muscles and fascial structures that allow it to function as the protector of intra-abdominal organs and to flex and extend the trunk and support the back.
Abdominal wall infections are rare other than as a complication of a prior mesh repair of abdominal fascia.

The four muscles we are going to look at are the Rectus Abdominus, External Oblique, Internal Oblique and Transverse Abdominus.
The first thing we need to think of when training the four abdominal muscles is to understand the mechanics of how these muscles work.
The Rectus Abdominus is responsible for flexion of the spinal column and compression of the abdominal cavity.

 Medical Article, Breast Reconstruction, Breast Augmentation, Reconstructive Surgery
The vertically orientated muscle fibers of both the internal and external oblique muscles assist in flexing the trunk, synergistic with the rectus muscles.
As the rectus muscle is the only one of the flexor group that has been surgically damaged, we may presume that the decreased abdominal wall strength is caused by resection of a part of the rectus muscle.
If the rectus muscles were not active and the trunk could not be stabilized, no sit-up or curl-up could be performed because the iliopsoas muscles would only be tilting the pelvis and lower lumbar spine, leaving the upper body immobile.

 CHAPTER 25: ABDOMINAL WALLS
Anteriorly, the abdominal wall includes the rectus abdominis muscles, and the aponeuroses of the three muscles (the external and internal oblique and the transversus) that form much of the side of the abdomen.
The anterior sheath is comprised of the aponeurosis of the external oblique and an anterior layer of the aponeurosis of internal oblique; the posterior sheath of the posterior layer of the internal oblique and the aponeurosis of the transversus abdominis muscle.
The external and internal oblique muscles and the transversus abdominis muscle are lateral (table 25-1).
