12 Best Rear Delt Exercises for Stronger, Balanced Shoulders

Rear delt exercises strengthen the back of your shoulders, helping improve shoulder balance, posture, and pulling strength. Understanding how to train the rear delts correctly matters because these muscles are often undertrained compared to the front delts, which can contribute to poor shoulder mechanics and discomfort over time.

In this guide, you’ll learn what rear delt exercises are, why they matter, and the 12 best rear delt exercises you can use to build stronger, more stable shoulders—whether you train at home or in the gym.

What Are Rear Delt Exercises?

Rear delt exercises are movements that primarily target the posterior deltoid, the muscle located on the back of the shoulder. The rear delts assist with:

Shoulder extension
Horizontal abduction (moving the arm backward)
External rotation and shoulder stability

According to Physiopedia, the posterior deltoid plays a key role in controlling arm movement and stabilizing the shoulder joint during pulling and overhead activities.

12 Best Rear Delt Exercises for Stronger, More Balanced Shoulders

Below are some of the most effective and widely recommended rear delt exercises used by trainers, physiotherapists, and strength professionals.

1. Bent-Over Dumbbell Reverse Fly

Why it works:
This movement trains shoulder horizontal abduction, one of the primary functions of the rear delts. The hip-hinged position minimizes assistance from the chest and front delts, allowing the posterior shoulder to work more directly while the upper back stabilizers support controlled motion.

How to do it:

Hinge at the hips until torso is nearly parallel to the floor
Keep a neutral spine with core lightly braced
Let dumbbells hang directly under the shoulders
Lift arms out to the sides with a slight elbow bend
Stop when upper arms align with the torso
Lower slowly back to the start position

Trainer tip:
If you feel this mostly in your traps, reduce the weight and slow the lowering phase.

2. Cable Reverse Fly

Why it works:
Unlike dumbbells, cables provide consistent resistance throughout the entire range of motion. This continuous tension increases time under load for the rear delts, which may help improve muscular endurance and control.

How to do it:

Set dual cables at shoulder height
Grab opposite handles with arms crossed
Step back slightly to create tension
Pull arms outward in a wide arc
Keep chest tall and shoulders down
Return slowly to the start position

Trainer tip:
Keep your ribs down and avoid leaning back to maintain rear delt focus.

3. Reverse Pec Deck Fly

Why it works:
The machine stabilizes the torso, reducing momentum and external variables. This allows greater isolation of the rear delts, making it useful for beginners or lifters struggling with strict form.

How to do it:

Sit facing the pec deck with chest against the pad
Adjust handles so arms are at shoulder height
Maintain a slight bend in the elbows
Pull handles backward in a controlled motion
Squeeze shoulder blades briefly
Return slowly to the start

Trainer tip:
Focus on moving your arms, not squeezing your hands—grip tension can shift work away from the shoulders.

4. Face Pulls

Why it works:
Face pulls integrate rear delt activation with scapular retraction and external rotation, supporting shoulder stability. This makes them valuable for posture-focused training and balanced shoulder programs.

How to do it:

Attach a rope to a cable at face height
Hold the rope with thumbs pointing back
Pull toward your face while flaring elbows outward
Squeeze shoulder blades together
Control the return phase

Trainer tip:
Think about pulling the rope apart at the end rather than pulling it straight back.

5. Chest-Supported Rear Delt Row

Why it works:
Chest support removes lower-body momentum and reduces spinal loading. The flared elbow position shifts emphasis away from the lats and toward the rear delts and upper back.

How to do it:

Set an incline bench at a low to moderate angle
Lie chest-down with dumbbells hanging
Pull elbows outward and back
Stop when elbows reach torso level
Lower slowly with control

Trainer tip:
Use lighter weights than standard rows and prioritize elbow path over load.

6. Wide-Grip Seated Cable Row

Why it works:
A wider grip and higher elbow position reduce lat dominance and increase posterior shoulder involvement, making this row variation more rear-delt friendly.

How to do it:

Attach a wide bar to the cable row station
Sit tall with chest lifted
Pull bar toward upper chest
Keep elbows flared out to the sides
Pause briefly, then return slowly

Trainer tip:
If you feel this mostly in your lats, widen your grip or reduce the range slightly.

7. Single-Arm Cable Rear Delt Fly

Why it works:
Single-arm training improves neuromuscular control and highlights side-to-side imbalances, which are common in shoulder musculature.

How to do it:

Stand sideways to the cable stack
Hold the handle with the far arm
Pull arm across the body and backward
Keep torso stable and shoulders level
Return slowly under control

Trainer tip:
Light resistance works best—this is a control exercise, not a max-effort lift.

8. Incline Dumbbell Reverse Fly

Why it works:
The incline bench reduces body sway and minimizes lower-back involvement, allowing the rear delts to perform most of the work.

How to do it:

Lie chest-down on an incline bench
Let arms hang straight down
Raise dumbbells outward with slight elbow bend
Stop at torso level
Lower slowly and evenly

Trainer tip:
Count the lowering phase to 3–4 seconds to increase rear delt time under tension.

9. Band Pull-Apart

Why it works:
Band pull-aparts reinforce shoulder positioning and scapular control with minimal joint stress, making them ideal for warm-ups or posture-focused routines.

How to do it:

Hold a resistance band at shoulder height
Keep arms straight but relaxed
Pull hands apart until arms form a “T”
Pause briefly
Return with control

Trainer tip:
Avoid arching the lower back—maintain a stacked ribcage and pelvis.

10. Rear Delt Raises (Standing)

Why it works:
This simple movement targets the rear delts through controlled shoulder extension and abduction, making it accessible for home workouts.

How to do it:

Hinge slightly forward at the hips
Hold dumbbells with palms facing inward
Raise arms diagonally backward
Keep neck neutral and shoulders relaxed
Lower slowly

Trainer tip:
If range shortens, reduce weight rather than forcing momentum.

11. High Row with Elbows Out

Why it works:
Pulling with elbows flared increases horizontal abduction demands, shifting work toward the rear delts instead of the lats.

How to do it:

Use a barbell, machine, or cables
Pull toward the upper chest
Keep elbows wide throughout the movement
Pause briefly at the top
Lower under control

Trainer tip:
Avoid excessive load—this variation prioritizes shoulder mechanics over strength.

12. Y-Raise on Incline Bench

Why it works:
The Y-raise emphasizes shoulder control, endurance, and coordination between the rear delts and lower trapezius, which supports healthy shoulder mechanics.

How to do it:

Lie chest-down on an incline bench
Hold light dumbbells with thumbs up
Raise arms overhead in a “Y” shape
Keep shoulders down and neck relaxed
Lower slowly

Trainer tip:
This exercise should feel challenging with very light weights—control matters more than load.

How Often Should You Train Rear Delt Exercises?

General resistance-training guidelines from ACSM recommend training each major muscle group at least two times per week. Rear delts are relatively small and often respond well to moderate volume and controlled technique.

A common approach is:

2–3 rear delt exercises per session
2–4 sets per exercise
10–15 controlled repetitions

Rear delt exercises are often placed later in the workout, after large compound pulling movements.

Why Rear Delt Exercises Matter for Shoulder Health

Rear delt exercises matter because the shoulder is a highly mobile joint that relies on muscular balance for stability. Many workouts emphasize pressing movements, which heavily recruit the front delts and chest, while the rear delts receive far less direct work.

Well-programmed rear delt exercises may help support:

Better shoulder posture and alignment
Balanced shoulder development
Improved pulling strength for rows and pull-ups
Reduced compensatory strain on the neck and upper traps

The American Council on Exercise (ACE) emphasizes balanced shoulder training to support joint health and long-term performance.

Warm-Up Before Rear Delt Exercises

Warming up before rear delt exercises helps prepare the shoulder joint, upper back, and nervous system for controlled pulling movements. A proper warm-up may support better muscle activation and reduce unnecessary strain.

A simple rear-delt-focused warm-up can include:

Light band pull-aparts to activate the posterior shoulders
Scapular retractions to encourage proper shoulder blade movement
Low-load reverse fly motions with slow, controlled tempo

Keep the warm-up short and easy, focusing on movement quality rather than fatigue.

Common Mistakes During Rear Delt Exercises

Some of the most frequent errors include:

Using weights that are too heavy
Shrugging shoulders instead of moving arms
Rushing through repetitions
Letting the lower back generate momentum

Keeping movements slow and controlled helps ensure the rear delts do the work.

How the Rear Delts Work During Shoulder Movements

The rear delts (posterior deltoids) help control arm movement and stabilize the shoulder joint, particularly during pulling and overhead actions. They are most active when the arm moves backward or away from the body.

Key rear delt functions include:

Shoulder horizontal abduction
Shoulder extension
Assisting external rotation with the rotator cuff

During exercises like rows, reverse flys, and face pulls, the rear delts work with the upper back to guide the arms backward and support proper shoulder blade movement. When rear delts are weak or undertrained, other muscles—such as the upper traps or lower back—may compensate, which can affect movement quality and shoulder control.

Breathing and Shoulder Control During Rear Delt Exercises

Proper breathing supports shoulder control and overall movement efficiency during rear delt exercises. Controlled breathing may help maintain stability through the torso and prevent excessive upper-trap tension.

General breathing guidelines:

Exhale gently during the pulling or lifting phase
Inhale during the controlled lowering phase
Keep ribs stacked over the pelvis to avoid excessive arching

Smooth breathing encourages better coordination between the shoulders and upper back, especially during slow, controlled repetitions.

Who Should Avoid or Modify Rear Delt Exercises

Most people can safely perform rear delt exercises when using appropriate resistance and proper form. However, some individuals may need to modify or temporarily avoid certain movements.

Extra caution is recommended for people who:

Have ongoing shoulder pain or limited shoulder mobility
Are recovering from a shoulder, neck, or upper-back injury
Experience sharp pain, numbness, or tingling during pulling movements

In these cases, reducing range of motion, using lighter resistance, or choosing supported exercises may be more appropriate. If symptoms persist, seeking guidance from a qualified healthcare or fitness professional is advised.
