Arnold Press
Front delts, Side delts


Shoulders / Beginner / Isolation (single joint)
A dumbbell isolation exercise for the front delts, with the upper traps assisting.
Why it hurts: The upper traps take over and the rotator cuff and lower traps, which protect swimmers' shoulders, do less.
✓ Instead: Use light weights, thumbs up, and raise in a Y at about 30° in front of the body with the shoulders down.
