Dumbbell Cuban Press
Rotator cuff, Side delts


Shoulders / Beginner / Compound (multi-joint)
A band exercise for the rotator cuff.
Why it hurts: The movement turns into a shoulder swing and the small cuff muscles do not work.
✓ Instead: Tuck a rolled towel between the elbow and ribs and keep it there.
Why it hurts: The rotator cuff is small; heavy loads make bigger muscles take over and can irritate the tendons.
✓ Instead: Choose a light band for 15–20 slow, controlled reps.
