The past three Fine Anatomy articles have examined movements of the shoulder and the shoulder girdle. Because the shoulder is an immensely complex structure, personal trainers must invest a significant amount of time and effort learning its “functional pathologies” and understanding basic anatomy in order to create sound exercise program design.
The arm (upper limb) rotates medially and laterally about a vertical axis (through the long axis of the humerus). This motion is produced by contraction of the rotator muscles along with other muscles of the upper limb.
TThe multiarticular complex of the shoulder gives rise to the dynamic movement potential of the arm at the glenohumeral joint. If it were not for the physiological necessity of the scapulo-thoracic “joint” (discussed in the previous Fine Anatomy column, “The Shoulder Girdle,” IDEA Personal Trainer, October 2003, p.36) and its role during abduction or flexion of the upper limb to elevate, rotate, tilt and swivel, the elementary movements of the arm would be greatly limited.
The Great Abs DebateIf you’re up to snuff on your anatomy and physiology, you know that the rectus abdominis is a single muscle. However, you may have found yourself caught up in the debate about whether you can train the upper and lower portion in different ways.

About 2 million people in the U.S. visit the doctor annually for rotator cuff problems (AAOS 2008), and at least 3% of adults will experience adhesive capsulitis, or frozen shoulder (Manske & Prohaska 2008). Multiple exercises can help prevent or postpone surgery, but what if they don’t seem to work? When regular shoulder exercises don’t help your client improve, or if they hurt too much, it’s time to start looking beyond the shoulder girdle.
