12 deltoid exercises for an effective at-home shoulder workout

Working the deltoid muscle doesn't only tone your arms, but protects the shoulder joint and prevents injury.

You may have never heard of the deltoid muscle — or perhaps you have, but aren't sure what they are exactly. But if you’ve ever worked at toning your shoulders, then you’ve definitely done exercises that target this muscle. 

What are the deltoid muscles?

The deltoid is a large muscle that covers the top of each shoulder joint. The deltoids are comprised of three parts: the anterior, middle and posterior deltoid. These fibers cover the upper arms to provide the round shape we’re accustomed to. But beyond aesthetics, they play a crucial role in various upper-body movements. By targeting and strengthening these muscles, you can reduce the risk of shoulder injuries and improve your overall shoulder stability. This is super important, especially if you are play sports or do strength training that involves a lot of shoulder movements. 

Deltoid exercises can improve posture, enhance upper-body strength and help you achieve that sculpted, athletic look. Having strong deltoids can also help you perform everyday movements with ease, like carrying groceries, lifting up a child or object off of the ground and even making your bed!
