“I ask not for a lighter burden, but for broader shoulders.”
Your shoulder muscles can make for a striking appearance. Wide shoulders are eye-catching symbols of health and strength and an important part of creating a V-shaped torso.
Athletically, your shoulders are the foundation for every action your arms take. Whether you’re pushing or pulling, or even lifting something with your arms by your sides, your shoulders take the brunt of the work.
On this page, you will find an introduction to shoulder muscle anatomy, links to the best shoulder exercises, and all our shoulder workouts and resources.
Shoulder Muscle Anatomy
Your shoulder muscles, or deltoids, consist of three distinct sets of muscle fibers: the anterior deltoid, lateral deltoid, and posterior deltoid. Or, in simpler terms: the front delts, side delts, and rear delts.
- Your front delt originates from the outer part of your clavicle, next to the clavicular part of your pectoralis major. It inserts in the front of your upper arm bone (humerus). The primary function of your front delt is to bring your arm forward (flexion), such as in pressing movements or front raises.
- Your side delt originates from your acromion – the bony process of your shoulder blade that forms the “roof” of your shoulder joint – and insert into the outside of your upper arm bone. The primary function of your lateral deltoid is to lift your arm out to your side (abduct), like in a lateral raise. It is also essential for keeping your shoulder joint in place when you are carrying or lifting things.
- Your rear delt originates from the back of your shoulder blade, partially covering your rotator cuff. It inserts on the outside of your upper arm, and its primary function is to bring your arm back (extend) and externally rotate it. It is a synergist to your lats in shoulder extension and a synergist to infraspinatus and teres minor in external shoulder rotation.
These are not separate segments but rather a continuous arrangement of muscle fibers that all converge into the same tendon, inserting on the outside of your upper arm bone.
Other groups of muscles that cross your shoulder joint are your chest, lats, and rotator cuff. Your trapezius muscle doesn’t cross your shoulder joint but attaches to your shoulder blade, which makes up the base of your shoulder joint.
For complete shoulder training, you should perform exercises that bring your arm …
- Forward (flexes your shoulder)
- Out to your side (abducts your shoulder)
- Backward (extends your shoulder)
If you perform exercises that involve each of these three movements, you will have trained all of your shoulder muscle fibers.
Shoulder Exercises
Which are the best shoulder exercises?
The answer to that question will depend on your goals and current fitness level, among many other factors.
Still, below are some of the best shoulder exercises many individuals can perform to build bigger, stronger shoulder muscles.
Note that these exercises will target different heads of your deltoid, and you will need to combine several of them for total shoulder development. Every exercise also has several possible substitutes that can work equally well, or even better, depending on your circumstances.
