The shoulders are the most widely used muscle in the upper body in my opinion. They function in almost every action that comes your way. The shoulders have almost 360 degrees of rotation
Yes, shoulders are a very important muscle but why is it that so many people can’t seem to develop a thick well balanced set of shoulders? Keep reading and we will figure out the answer to that question in time.
Shoulders have 3 components :
o Function: Flexion, Medial Rotation
o Location: Front portion of the shoulder girdle
o Exercise: Barbell Shoulder Press
o Function: Abduction
o Location: Middle/Side of the shoulder
o Exercise: Dumbbell Side Laterals
o Function: Extension, Lateral Rotation
o Location: Back of the shoulder
o Exercise: Bent Over Dumbbell Rear Delt Raise With Head On Bench
What you can see from the anatomy information above is the shoulder is really made up of 3 different small muscle groups. Many beginners treat the shoulder as one muscle group, and train it like the chest; presses, presses and more presses.
All exercises should be performed in perfect form because bad form or habits that you start now will follow you and will lead to lack of progress or worst off injury in the future.
