The Abdominal Muscles

The Abdominal musclesWhen you start a training program is is a good idea to become familiar with the muscles that make up your body. The more knowledge you have of  the muscles you're working, the better you'll be able to judge what is needed to make improvements. This post covers the mid-section or core.

The core muscles of the mid-section do much to stabilize and support the torso so it's well worth spending time to train this area properly. The main muscles of the mid-section are as follows:

Rectus abdominis – this is a large flat muscle that covers most of the front mid-section from the lower chest to the pubic bone. Above the navel it consists of three pairs of rectangular sections stacked on top of each other This is what can form the musch sought after six-pack.

Obliquus abdominis – this muscle runs diagonally along the side of the mid-section from the lower ribcage to the pubic area. There are two muscles on each side, with internal obliques lying underneath the external obliques. The obliques help your torso to flex to the side, twist at the waist and bend it forwards.

Transversus abdominis – this is the deepest of the abdominal muscles and consists of a thin strip that runs horizontally across the abdomen. This muscle helps keep the internal organs in place, forces out the breath and stabilises the spine.

Erector spinae – this large muscle group runs along the side of the lower spine. Consisting of a pair, the erector spinae keeps the spine erect and helps twisting at the waist.
