Know
Your Muscles -
The Shoulders And Arms
By Richard Mitchell
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.
