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.
