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 chest and upper back.
Although they are two distinct areas, the chest and the upper back will be
considered together because achieving a muscular balance between them is
crucial, particularly in relation to maintaining good posture. Creating an
imbalance between the two is likely to result in injury.
The main muscles found in the chest and uper back are as follows:
1. Pectoralis major - these are the large chest muscles found to either side of
the breastbone. Its main job is to bring the upper arm inwards across the body,
a movement that is known as horizontal adduction.
2. Latissimus dorsi - this is the largest back muscle that runs from the lower
back to the upper arm bone. It pulls the upper arm towards the body and acts as
an internal rotator of the upper arm.
3. Trapezius - this muscle runs from the mid spine to the shoulder and then to
the neck. Its main role is to faciltiate movement of the shoulder blades.
