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.
