Barbell Shrugs
The barbell shrug is an upper-back isolation exercise where you hold a barbell at arm's length in front of your thighs and lift your shoulders straight up towards your ears. It trains the upper trapezius and levator scapulae, and the short range and strong position let it be loaded heavier than almost any other upper-body exercise.

What muscles does the barbell shrugs work?
Primary movers
- Upper trapezius
Assisting muscles
- Levator scapulae
- Middle trapezius
- Forearm flexors
The upper trapezius elevates the shoulder blades, lifting them towards the ears. A shrug isolates exactly that action, which is why it is the most direct trap exercise there is.
The levator scapulae, which runs from the neck to the top of the shoulder blade, assists elevation. The middle traps contribute a little to stabilise the shoulder blades, especially if you squeeze them slightly back at the top.
Fibre direction matters for how you shrug. The upper traps pull upward and slightly inward, so the strongest line of pull is straight up, with the shoulders finishing slightly back. Rolling the shoulders forward or backward in a circle adds no extra trap work.
Because the bar sits in front of the body, a barbell shrug pulls the shoulders slightly forward. That is one reason some lifters prefer dumbbells or a trap bar, which keep the load at the sides.
Grip is often the limiting factor. The traps can handle far more than the hands can hold for a full set, which is why lifting straps are common on heavy barbell shrugs.
How to do the barbell shrugs
Setup
- 1
Set a barbell in a rack at around mid-thigh height.
- 2
Grip the bar with an overhand grip just outside the thighs, using straps if your grip is the weak link.
- 3
Lift the bar out of the rack and stand tall with feet hip-width apart.
- 4
Let your arms hang straight and your shoulders drop as low as they comfortably go.
Execution
- 1
Lift your shoulders straight up towards your ears as high as they will go.
- 2
Keep your arms straight. The elbows should not bend at all.
- 3
Pause for one to two seconds at the top and squeeze the traps.
- 4
Lower the shoulders slowly until you feel a stretch in the upper traps.
- 5
Keep your head neutral rather than jutting the chin forward.
- 6
Stand tall throughout without leaning back or using the legs.
Common barbell shrugs mistakes
Rolling the shoulders
Circling the shoulders forward or backward on each rep in the belief that it hits more of the traps. It adds strain to the shoulder joint without adding any trap work.
The fix: Move straight up and straight down. A slight backward squeeze at the top is fine, a full roll is not.
Bending the elbows
Pulling the bar up with the arms, which turns the shrug into a partial upright row and lets the biceps and delts take over.
The fix: Keep the arms straight like ropes. Only the shoulders move.
Bouncing heavy weight through a tiny range
Loading far more than you can control and bouncing it a couple of inches. The traps get little stimulus and the neck gets a jolt.
The fix: Use a load that lets you reach full elevation with a pause at the top and a controlled stretch at the bottom.
Jutting the head forward
Pushing the chin forward to help each rep, which shifts stress onto the neck.
The fix: Keep your head stacked over your spine and your gaze straight ahead.
How many sets and reps?
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Hypertrophy | 3–4 | 10–15 | Heavy, 1 s pause at the top | 60–90 s |
| Strength | 3–4 | 6–8 | Very heavy, straps | 2 min |
| Trap endurance | 2–3 | 15–20 | Moderate | 60 s |
The traps already work hard in deadlifts, rows and carries, so many lifters need little direct trap work. If you want bigger traps, two to four sets of shrugs once or twice a week is enough. Use straps when grip limits the set, because otherwise your forearms will stop the set before your traps do. A pause at the top is the simplest way to make a given weight more effective.

Dumbbell Shrugs
AlternativeWeights at the sides allow a straighter line of pull and a slightly longer range, at a lower total load.
Trap Bar Shrug
AlternativeNeutral handles at the sides combine the heavy loading of a barbell with the shoulder position of dumbbells.
Behind-the-Back Barbell Shrug
AlternativeHolding the bar behind you pulls the shoulders back and shifts slight emphasis to the middle traps.
Farmer's Carry
HarderHolding heavy weights while walking trains the traps isometrically along with grip and core.
Frequently asked questions
What muscles do barbell shrugs work?
Mainly the upper trapezius, which lifts the shoulder blades towards the ears. The levator scapulae assists, and the forearms work hard to hold the bar. The middle traps contribute a little if you squeeze the shoulders back slightly at the top.
Are barbell or dumbbell shrugs better?
Barbell shrugs allow heavier loads and are easier to progress. Dumbbell shrugs allow a more natural line of pull at the sides and a slightly longer range. Both build the traps well, and alternating between them is a reasonable approach.
Should I roll my shoulders when shrugging?
No. The upper traps pull the shoulder blades up, so moving straight up and down is the most effective path. Rolling adds stress to the shoulder joint without any extra trap work.
Should I use straps for shrugs?
If your grip gives out before your traps, yes. The traps can handle more weight than most people can hold for 10 to 15 reps, and straps let the target muscle set the limit rather than your hands.
How heavy should shrugs be?
Heavy enough that 10 to 15 reps with a full range and a short pause at the top is challenging. Many people can shrug more than they deadlift for reps, but only if they cut the range short. Range and pause first, then load.
