Cannonball delts? That's the goal, right?
Well, here's how the deltoids work to help you get to your goal of massive boulder shoulders!
The deltoids can be broken down into three parts: the anterior, posterior, and middle.
The anterior is the bulky part in the front of your shoulders. It performs flexion, abduction, horizontal adduction, and internal rotation of the shoulder.
Exercises to target these motions would be the classics of bench press, shoulder press, dips, and front raises—pretty standard stuff here.
For posterior delts, these aren't targeted as much, but they're essential to healthy shoulders, so DON'T NEGLECT THEM!
They perform extension, abduction, adduction, horizontal abduction, and external rotation of the shoulder.
Exercises to target these movements are the good ol’ face pulls (make sure your thumbs are pointing behind you), W-raises, lateral raises and shoulder press.
Lastly, we have the middle head. This portion is responsible for abduction and flexion of the shoulder, not too much action here but they still are strong and should not be neglected.
Exercises are the shoulder press (yes, the shoulder press targets all three heads) and lateral raises.
The shoulder is a complex joint that relies on many muscles for movement and stability. No one muscle is more important than the others. A healthy shoulder has strong muscles all around it! It is a relatively unstable joint and requires healthy, strong muscles to keep it stable and moving. Keep it healthy and keep it strong!
