Groups of abdominal

In the center of the abdomen is located the belly button, which serves to locate the upper abdominal muscles above the navel, and lower by beneath.

We have 4 groups of abdominal muscles which combine between them to cover internal organs and it allows all type of movement.

The rectus abdominis, is the group abdominal which has the famous ‘package’ or six pack, so characteristic. Its main function is to allow the movement of the body between the ribcage and pelvis.

We also have transverse muscles in the abdomen, they are very long and triangular, are located on the sides of the abdomen and are called abdominal oblique. They are divided between external and internal.

The transverse abdominals are the deeper muscle layer. Its main functions are to stabilize the trunk and keep the inner abdominal pressure.

We also have muscles between the centerline of pubic reaching just the edge of our chest, this group of muscles is called linea alba.

Basic muscle groups

The deep abdominal muscles, along with the muscles of the back, constitute the so-called Group of “basic” muscles that help keep the body balanced and stable, and protect the spine.

This group of muscles are composed of deep abdominal muscles and some back muscles, those who touch to the spine and pelvis. Some of these muscles include the transverse abdominal, pelvic floor muscles and oblique muscles.

Another muscle is the multifidus. It is a deep muscle of the back that runs along the spine. Together with the transverse muscles of the abdomen, it serves to increase the stability of the spine as well as to protect us from back injuries. Usually they train together with the abdominals, although is not a abdominal muscle.
