Becoming familiar with the muscles that make up your body has more benefits than
simply allowing you to talk shop with your training partners. The more familiar
you are with the muscles you're working, the better you'll be able to judge
what's needed to make improvements. In this article we'll get to know the
muscles that make up the mid-section.
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:
1. Rectus abdominis - this is a large flat muscle wall 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
and is better known as the six pack.
2. 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 help in
bending the torso forwards.
3. 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 stabilizes
the spine.
4. 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.
