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.
