Know Your Muscles The Mid Section
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.
BONUS : Know Your Muscles - The Shoulders And Arms
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 shoulders and arms.
Shoulders and arms work together but they require significantly different exercises to make them bigger and stronger. The main muscles found in these areas are as follows:
1. Deltoid - this is comprised of three separate segments that cover the shoulder and run a few inches down the arm. The anterior deltoid raises the arm to the front. The middle deltoid raises the arm to the side. The posterior deltoid draws the arm backwards.
2. Rotators - these are small muscles of the rotator cuff that control small movements of the upper arm. Consisting of an internal rotator, external rotator and supraspinatus they are used in lifting and throwing actions.
3. Biceps brachii - the biceps covers the front part of the upper arm and consists of a long head and a short head. The long head crosses the shoulder joint and works with the front deltoid to raise the arm to the front.
4. Triceps brachii - the triceps covers the the back of the upper arm and consists of three sections - the long, lateral and medial heads. The role of the triceps is to straighten the arm at the elbow.
5. Brachialis - this muscle lies between the upper arm bone and biceps. It helps the biceps to bend the elbow when the palm is facing sideways.
6. Forearm muscles - the forearms consist of many little muscles called flexors and extensors. The largest forearm muscle is the brachioradialis that lies close to the elbow.
