Seated rear delt fly
The Seated Reverse Dumbbell Fly targets the rear delts and upper-back stabilizers, helping correct rounded-shoulder posture caused by excessive pressing work. Performed seated with a slight forward lean, you open the arms out to the sides under control. It is essential for shoulder balance, stability, and long-term joint health in strength training.

Key Benefits
- Builds rear delts for better posture and shoulder balance.
- Offsets chest-dominant training to reduce muscular imbalance.
- Improves shoulder stability for rows and pull-down variations.
- Prepares you for cable reverse fly and more advanced rear-delt work.
Instructions
- In the starting position, seated, keep your torso bent parallel to the ground
- Position your arms aligned with your shoulders while holding the dumbbells
- Raise your arms to the side until your elbows align with your torso
- Lower your arms in a controlled manner
Tips
- Avoid using momentum or sudden movements with your arms and torso
- Do not arch your torso
- Do not let your torso rise while performing the movement
Restrictions
Avoid if you experience shoulder pain during arm opening or have a rotator cuff injury history. Individuals with limited shoulder mobility should reduce range and use light weights. Beginners and older adults must focus on control rather than load. If neck tension appears, keep the head neutral and reduce torso inclination. Stop if sharp joint pain occurs.
Common Mistakes to Avoid
- Swinging the torso to lift heavier weight.
- Shrugging the shoulders instead of isolating rear delts.
- Using excessive range and losing control at the end.
