Top 7 Rear Delt Exercises To Make Them Grow

Updated on  May 12, 2022 by  Welcyon Team

The rear delts, also known as posterior deltoids, are often skipped during a workout session by most people. Strong shoulders can help you lift, pull, push and support yourself throughout the day. Whether you are at the gym, at home, at your job, or doing regular chores, strong shoulders can help make you look buff and fit and make strenuous tasks more manageable.

However, you will need to build body strength through regular exercise to enjoy the benefits of strong rear delts. The front of the shoulders or anterior delts are regularly used in most exercises and daily activities. They are the least ignored of the two deltoids in your shoulder.

Therefore, adding a set of exercises to your daily regime is necessary to get your rear delts properly pumping!

If you don't already have a rear delt exercise incorporated into your daily workout, or if you are looking for others to strengthen your rear delts, then look no further. This guide shall look at top bodyweight rear delt exercises, their benefits, and the exact steps you can follow.

We promise that incorporating some of our favorite rear delt exercises into your workout regime will help you gain shoulder strength, help with better posture, and boost body confidence. Let's get straight to it!

What Is The Rear Delt?

The rear delts or posterior deltoids are the rear deltoids in your shoulder. It is one out of three present in the area.

Deltoid muscles are triangular, hence the word delt/deltoid. It is derived from the Greek word Delta. Posterior and anterior simply mark the location and position of each muscle in your shoulder and upper body.

The rear delts cover the glenohumeral shoulder joints to form the shoulder curve. Rear delts start at the base of the scapula and spine. They insert into the deltoid tuberosity of the lateral humerus on both sides. 

Our shoulders are made up of three muscles:

Anatomy Of The Shoulder

Front

Anterior Deltoid or Front Delt

The anterior deltoid is located at the front of the shoulder. It's responsible for helping the upper arm and shoulder rotate inwards.

Front raises, pushups, bench pressing, and pushing actions are all aided by the front deltoid.

Side

Medial/Lateral Deltoid or Side Delt

The lateral deltoid is present on the side of the upper arms. Just as the name suggests, this muscle helps aid rear lateral raises, pulling your arm backward or tugging a cord behind you.

ReaR

Posterior Deltoid or Rear Delt

Rear delts are present at the back of the shoulder. They are responsible for helping the shoulder perform lateral rotations and extend the arms.

Strong rear delts help maintain good posture, help perform exercises like reverse flys, and aid in arm plus body coordination.

Top 7 Rear Delt Exercises

Now that you know what the rear delts are and why it's essential to work these muscles out during your daily workout regime, it is time to look at a few shoulder exercises.

We shall go into an in-depth description for each so that you can easily incorporate these into your workouts.

This section shall follow with another one that explains how the best rear delt exercises can benefit you. Stick till the end to find out!

The Advantages Of Rear Delt Exercises

As promised, we have compiled a section that will discuss the benefits of performing dumbbell rear delt exercises and those that build upper body strength.

Keep reading to find out why you should start rear delt training straight away! Let's look at the main advantages below:

Shoulder or Rear Delt Strength

Adding rear deltoid exercises to your daily shoulder routine can help increase and build shoulder strength.

These exercises specifically target the rear deltoid muscle to help you add strength, build muscle mass and increase bone density.

You will be able to work out better, do daily chores more efficiently, and be less prone to shoulder injuries.

Improved Posture

If you are someone who has bad posture or slumps while sitting, then a rear delt workout is a solution.

A rear deltoid workout helps straighten and strengthen the back and shoulder muscles which helps you improve your posture both while sitting and standing.

Increase Strength

This one is obvious. You exercise to build strength, and rear deltoid exercises work similarly. Better shoulder strength makes arm movements more powerful and stable.

Performing posterior deltoid exercises will help you perform other exercises that depend on shoulder strength better.

These include the bench press, deadlift, dips, pull-ups, pushups, and overhead press.

Positive Body Image

Training the rear delts helps improve the look of your body. This also helps create a positive body image in your head, which boosts self-confidence.

You will feel more attractive and appealing when you dress up and more willing to participate in social interactions.

Decreased Risk Of Injuries

Strong muscles are less prone to injuries. Therefore, training the rear delts can help you reduce shoulder pain, stress, and stiffness. They also reduce the chances of injury to rotator cuffs.

Conclusion

We hope you found our guide on the best rear delt exercises helpful. Following most or all of the best rear deltoid exercises above will help you strengthen your shoulders and improve body posture and stability.

Follow the steps correctly and watch tutorials to clear out any confusion. You can also reach out to your gym trainer to follow a proper diet and ensure you follow your rear deltoids workout correctly.

Do not hesitate to ask your trainer about how you can incorporate any shoulder routine or other rear delt exercises into your daily regime. Good luck!
