Barbell Shrug
The barbell shrug is a trap isolation exercise: standing with a barbell held at arm's length, you lift your shoulders straight up towards your ears and let them back down under control. It works the upper trapezius and the levator scapulae, the muscles that raise the shoulder blades, and it is usually the heaviest of the common isolation lifts.
Also called: BB Shrug, Shrugs, Barbell Shoulder Shrug, Standing Shrug · Equipment: barbell · Pattern: isolation
Step by step
- Set the bar in a rack at about mid-thigh height, or deadlift it from the floor. Hold it with an overhand grip just outside your thighs, using lifting straps if you use them.
- Stand tall with your arms straight, ribs down, neck long and chin slightly tucked.
- Brace your trunk and let your shoulders sink down to a full stretch at the start.
- Shrug your shoulders straight up towards your ears as high as they go, keeping your arms straight.
- Hold the top position for about a second.
- Bring your shoulders back down under control to the full stretch, then start the next rep.
- After the last rep, return the bar to the rack, or bend your knees and hips with a flat back to set it down.
- Shoulders straight up to your ears
- Hold the top for a second
- Arms straight, like hooks
- Neck long, chin tucked
- All the way down to a full stretch

What goes wrong, and the fix
Rolling the shoulders in a circle
Fix: Shrug straight up and bring your shoulders straight back down.
Bending the elbows
Fix: Keep your arms straight throughout, as if your hands are hooks.
Pushing the head forward
Fix: Keep your neck long and chin tucked, and move only your shoulders.
Bouncing short reps
Fix: Shrug fully to the top, hold for a second, then bring the bar down slowly.
Grip giving out before the traps
Fix: Use lifting straps so your grip no longer limits the set.
What the research says
Muscle growth · first choiceStrengthRehab & prehabGeneral fitnessSport performanceEndurance
- Load and reps — Research comparing loads finds muscle growth is similar across a wide range of loads when sets are taken close to failure. Shrugs are commonly trained heavy, with grip often the limit.
- Effort — Studies show sets that finish a few reps short of failure capture most of the growth benefit; true failure adds only a small extra effect.
- Volume — Research links more weekly sets for a muscle to more growth, with diminishing returns. Deadlifts, rows and carries also work the traps, and counting such indirect work improves volume estimates.
- Trap activity — In EMG studies, the shrug produced the highest upper-trap activity of ten common shoulder-blade exercises. Starting with the arms slightly out to the sides raised activity in both the upper and the lowest trap fibres. EMG shows activity, not growth.
- Straps — Lifting straps are widely used so grip does not limit the set. There is no direct research on straps and trap growth.
