What Is the Reverse Dumbbell Fly?

The reverse dumbbell fly, also known as the bent-over lateral raise, is a resistance exercise that primarily targets the posterior deltoids, rhomboids, and trapezius muscles. This exercise is performed by hinging at the hips and raising dumbbells out to the sides, mimicking the motion of a bird flapping its wings.

Unlike standard pressing or pulling exercises, the reverse dumbbell fly isolates the rear delts and upper back, which are often neglected in many traditional shoulder workouts.

“The reverse fly targets the rear deltoids, which are often underdeveloped compared to the front and side delts, helping to correct shoulder imbalances.” — Contreras et al., Journal of Strength and Conditioning Research


Benefits of the Rear Dumbbell Fly for Shoulder Strength

1. Balanced Aesthetic and Physique

The reverse dumbbell fly plays a crucial role in sculpting the shoulders. Strengthening the rear delts helps improve shoulder symmetry, contributing to a well-rounded shoulder appearance. When paired with exercises that target the front and side deltoids, the reverse fly helps achieve balanced shoulder development.

2. Shoulder Stability

The posterior deltoids are key to shoulder joint stability. By engaging these muscles, the reverse dumbbell fly enhances overall shoulder control and performance in other lifts, such as bench presses and overhead presses. This exercise also helps maintain proper posture, especially when performing pushing movements.

3. More Versatility

The reverse dumbbell fly is highly adaptable. You can perform it in various positions, including seated, bent over, or lying face down on an incline bench. This allows the exercise to be tailored to different body types and fitness levels, while still providing great results for shoulder strength and mobility.


Muscles Worked in the Rear Dumbbell Fly

Muscle Group Role in the Movement
Posterior Deltoid Primary muscle responsible for shoulder abduction and external rotation
Rhomboids Retract the scapula, improving shoulder stability
Trapezius (Upper & Middle) Assist with scapular movement and control
Infraspinatus & Teres Minor Rotator cuff muscles aiding in shoulder stabilization

Strengthening these muscles with reverse dumbbell flies improves posture, shoulder balance, and upper body strength.


Proper Form and Technique for Performing the Rear Dumbbell Fly

How To Do Rear Dumbbell Fluys - Step-by-Step Instructions

  1. Set Up Your Stance

    • Hold a dumbbell in each hand with palms facing inward (neutral grip).

    • Stand with feet hip-width apart, knees slightly bent, and hinge at the hips until your torso is nearly parallel to the ground.

  2. Engage Your Core

    • Engage your core to stabilize your spine and avoid excessive arching of your back.

  3. Perform the Fly Motion

    • With a slight bend in your elbows, raise the dumbbells out to the sides, keeping your arms at about a 45-degree angle.

    • Focus on leading with your elbows rather than your hands to ensure the rear delts are fully engaged.

  4. Squeeze at the Top

    • At the top of the movement, squeeze your shoulder blades together to fully engage your rhomboids and trapezius muscles.

  5. Lower Under Control

    • Slowly return the dumbbells to the starting position, maintaining tension in your shoulders.

  6. Reps and Sets

    • Perform 3–4 sets of 12–15 reps with a light to moderate weight to ensure strict form.


Common Mistakes to Avoid When Doing the Rear Dumbbell Fly

Mistake Correction Tip
Using too heavy a weight Start with light weights to master form; avoid swinging.
Elbows dropping below shoulder height Keep elbows at shoulder level or slightly above.
Leaning too far forward Maintain a neutral spine and engage your core throughout.
Jerking the weights Perform the movement slowly and under control.

Progression and Variations of the Rear Dumbbell Fly

Progression:

Start with light dumbbells to master the movement. Gradually increase the weight as you build strength. Progress by adding more sets or incorporating advanced variations.

Variations:

  1. Incline Bench Reverse Fly – Lie face down on an incline bench to isolate the rear delts more effectively.

  2. Standing One-Leg Reverse Fly – Perform the fly while balancing on one leg to challenge stability.

  3. Resistance Band Reverse Fly – Use a resistance band for added tension throughout the range of motion.


How to Incorporate the Rear Dumbbell Fly into Your Shoulder Workout Routine

The reverse dumbbell fly is an excellent accessory exercise to target the rear delts and improve shoulder stability. Integrate it into your shoulder workouts in the following ways:

Post Compound Movements

After performing overhead presses or bench presses, use the reverse dumbbell fly to isolate the rear delts and balance out shoulder development.

SuperSet or Finisher

Pair the reverse dumbbell fly with lateral raises or face pulls for a well-rounded shoulder workout. Perform them back-to-back for 3–4 sets of 10–12 reps each.

Frequency

Aim to incorporate reverse dumbbell flies 2–3 times per week to target the rear deltoids effectively without overtraining.


Tips for Maximizing Deltoid Gains with the Rear Dumbbell Fly

  1. Mind-Muscle Connection
    Focus on the rear delts throughout the entire range of motion. Feel the contraction and avoid using momentum.

  2. Supersets and Drop Sets
    Combine reverse dumbbell flies with other rear deltoid exercises like face pulls or band pull-aparts to maximize muscle activation.

  3. Adjust Angles
    Change the angle by using an incline bench or performing standing variations to target different parts of the rear delts.

  4. Form Over Weight
    Always prioritize proper form over heavier weights to prevent injury and ensure effective muscle recruitment.


Safety Precautions for Beginners and Those with Shoulder Injuries

For beginners, start with light weights and focus on mastering form before progressing to heavier dumbbells. It's important to warm up properly and engage in dynamic stretches to enhance mobility and flexibility in the shoulder joints.

If you have pre-existing shoulder injuries, consult a healthcare provider or physiotherapist before attempting this exercise. In some cases, using resistance bands or light weights can provide the same benefits without stressing the shoulder joint.


Sample Shoulder Workout Routine Including the Rear Dumbbell Fly

Exercise Sets Reps
Overhead Dumbbell Press 4 8–12
Lateral Raises 3 10–15
Reverse Dumbbell Fly 3 12–15
Face Pulls (or Band Pull-Aparts) 3 12–15

This shoulder routine balances strength and hypertrophy and integrates the reverse dumbbell fly to ensure comprehensive development of all three deltoid heads.
