Reverse Flyes With External Rotation

This move is like a bear doing a proud chest puff and a careful paw twist. You sweep your arms out like big wings, then rotate to show your paws to the sky. Go light, move slow, and let your rear delts and rotator cuff do the work so your shoulders feel as sturdy as a tree trunk.

Instructions

1. Set up with light dumbbells (or cables) and hinge at the hips to a near-parallel torso, spine neutral, knees slightly bent.
2. Let arms hang under shoulders with a slight bend in the elbows; brace your core and keep your neck long.
3. Start by pulling the shoulder blades back and down (retract and depress).
4. Perform a reverse fly: raise the upper arms out to the sides until roughly in line with your torso.
5. At the top, externally rotate: rotate the forearms so the hands move from palms facing down/in to thumbs up or palms forward (as comfortable), keeping elbows near shoulder height.
6. Pause briefly, then reverse the rotation and lower the arms under control to the start.
7. Repeat for controlled reps, keeping tension in the upper back and rear delts.

Benefits

• Strengthens rear deltoids for balanced shoulder development
• Improves scapular control and upper-back strength for posture
• Trains rotator cuff external rotators for shoulder stability
• May help reduce risk of shoulder irritation from pressing-dominant training
• Enhances control in overhead and pulling movements

Key Points

• Keep a slight bend in your elbows throughout the movement.
• Ensure your back remains flat and your core engaged.
• Perform the movement in a controlled manner.
• Focus on squeezing your shoulder blades together.

Common Mistakes

• Using weights that are too heavy and turning it into a swing
• Shrugging shoulders up toward the ears instead of keeping them down
• Overextending the low back to create range of motion
• Letting elbows drop too low during the rotation phase
• Rushing the external rotation and losing scapular control
• Locking elbows straight and stressing the joint
