Dumbbell Shrug
The dumbbell shrug is a standing lift in which you raise your shoulders straight up towards your ears while holding a dumbbell in each hand at your sides. It directly trains the upper trapezius and the small muscles that lift the shoulder blades, and it can be done one arm at a time.
Also called: DB Shrug, Dumbbell Shoulder Shrug · Equipment: dumbbell · Pattern: isolation
Step by step
- Stand tall with your feet about hip-width apart, holding a dumbbell in each hand at your sides, palms facing your body.
- Let your arms hang straight and your shoulders sit fully down so the traps start from a stretch.
- Brace your trunk and keep your chin level, eyes looking forward.
- Shrug your shoulders straight up towards your ears as high as they will go, keeping your arms straight.
- Hold the top for about a second.
- Bring your shoulders back down under control to the fully stretched start position.
- Repeat for the set, then set the dumbbells down at your sides.
- Shoulders straight up to the ears
- Arms stay long, like ropes
- Hold the top for a second
- Full stretch at the bottom
- Chin level, eyes forward

What goes wrong, and the fix
Rolling the shoulders in circles
Fix: Move your shoulders straight up and straight down only.
Bending the elbows
Fix: Keep your arms straight and relaxed and lift only with your shoulders.
Short, bouncing reps
Fix: Lift as high as you can, hold a second, then let the shoulders sink fully.
Pushing the head forward
Fix: Keep your chin level and your ears over your shoulders throughout.
Grip giving out before the traps
Fix: Many lifters use lifting straps so grip does not limit the set.
What the research says
Muscle growth · first choiceStrengthRehab & prehabGeneral fitnessSport performanceEndurance
- Load and effort — Research finds muscle growth is similar across a wide range of loads when sets are hard, and that taking sets to true failure adds only a trivial-to-small benefit. Shrugs are commonly done for about 8–15 reps with a pause at the top.
- Volume — Research links more weekly sets for a muscle to more growth, with diminishing returns. Rows and deadlifts also train the traps, so many programmes use shrugs as a small top-up.
- Range of motion — Meta-analyses find full range of motion gives equal or greater strength gains than partial range, so a full stretch and a full lift are common practice.
- Muscle activity — In an EMG study of shoulder-blade exercises, the one-arm shrug produced the highest upper-trap activity of the ten exercises tested. Activity is not growth.
- Tempo — Studies show growth is similar across rep speeds from about half a second to eight seconds when sets are hard.
