Delts and traps in one clean pull.
Keep elbows above the wrists and don't pull past the shoulders to protect the joint.
The dumbbell upright row drags the weight up the front of your body with your elbows leading, which puts the side delts under load through a range most pressing never touches. Your traps take over near the top and your biceps assist the pull throughout, making it a dense little three-for-one for the shoulder girdle. Dumbbells beat a fixed bar here because each hand can find its own path, sparing your wrists and shoulders the forced position.
They get that reputation from people pulling a fixed bar too high with a narrow grip. With dumbbells, each arm finds a comfortable line, and stopping when your elbows hit shoulder height keeps the joint out of the pinch zone.
Both hit the side delts, but the upright row adds real trap and biceps involvement and lets you handle more weight. Lateral raises isolate more strictly, plenty of good programmes use both.
Roughly shoulder-width, and let the dumbbells drift slightly apart as they rise. The wider, elbow-led path keeps the work on delts and traps instead of grinding your wrists.
