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.
