7 Best Rear Delt Exercises for Big, Strong Shoulders

Broad, well-defined shoulders are the hallmark of a commanding physique—but building them requires more than a frontal attack

If you want fully developed shoulders, it’s essential to make rear delt exercises a regular part of your training.

“The rear deltoids are the unsung heroes of the upper body,” says personal trainer Amanda Dale, MA, ACE-CPT.

They provide power in rowing movements, help with stability in pressing movements, and are largely responsible for the lean, toned appearance of the mid-to-upper back, he adds.

Unfortunately, Dale says, the rear delts are often the weakest of the three heads that comprise the deltoid.

This is largely the consequence of a sedentary lifestyle, which, not coincidentally, often counts poor posture among its casualties.

If you don’t address the muscular imbalance between the front and back of your shoulders, you could end up with poor shoulder mobility and mechanics—and potentially set yourself up for shoulder injury in the process.

To get you started, we’ve rounded up seven of the best rear delt exercises to incorporate into your routine.

1. Dumbbell reverse fly

Deltoid Anatomy

Anatomy of the shoulder muscles  Best rear delt exercises

Your rear delts are anatomically referred to as the posterior head of the deltoid, joining the anterior and lateral heads to form the entire deltoid muscle.

The three heads originate along the scapula (shoulder blade) and collarbone and attach midway down your humerus (upper arm).

The rear delts join the shoulders and back and are technically part of your posterior chain.

This means you can effectively hit your rear delts with both shoulder and back exercises.
