Shoulders
Shoulder External Rotation with Dumbbell
A foundational isolation movement designed to strengthen the rotator cuff and improve overall shoulder stability.
How to perform.
Follow the sequence — setup is half the lift.
Lie on your side on a flat bench or a mat with your legs stacked and your head supported by your bottom arm.
Hold a light dumbbell in your top hand and tuck your elbow firmly into your side, creating a ninety-degree angle at the elbow.
Place a small rolled towel between your elbow and your ribcage to ensure proper alignment and constant tension.
Rotate your forearm upward toward the ceiling as far as your range of motion allows while keeping the elbow pinned to your side.
Pause for a moment at the top of the movement to feel the contraction in the back of the shoulder.
Lower the dumbbell slowly back to the starting position in front of your stomach under complete control.
Complete all repetitions on one side before flipping over to train the opposite shoulder.
Common mistakes.
Fix these first — they cost reps, kilos, and joints.
- Using excessive weight which causes the elbow to lift away from the torso.
- Using momentum or swinging the body to help lift the weight.
- Over-rotating the shoulder past a natural and comfortable range of motion.
- Allowing the wrist to curl or bend during the lift instead of keeping it neutral.
Muscles worked.
The primary movers do the work; the stabilizers keep the path honest.
