Barbell Shrug
The barbell shrug is the simplest trap exercise: you hold a barbell at arm's length and lift your shoulders straight up toward your ears. It isolates the upper trapezius, the muscle between your neck and shoulders, and it lets you load that small movement heavily. A full lift and a short hold matter more than the weight on the bar.
How to do the barbell shrug
Set the bar in a rack at about mid-thigh height and stand close to it with your feet about hip width apart.
Take an overhand grip just outside your thighs, lift the bar out of the rack and stand tall with straight arms.
Let your shoulders hang down fully, keep your chest up and your neck in line with your spine.
Raise your shoulders straight up toward your ears until they will not go any higher, keeping your arms straight.
Hold the top for a moment, then lower your shoulders under control until they hang down again.
Setup for the barbell shrug
Start from a rack, not the floor. Set the safety pins or hooks at about mid-thigh, so you can lift the bar out with straight arms and a flat back, the same way you will put it back. Grip it overhand, hands just outside your thighs, and wrap your thumbs around the bar. A mixed grip, one palm forward and one back, lets the bar twist, so use straps instead once your hands give out.
Bracing and breathing
Stand tall with your chest up and your midsection braced, as if you were about to be pushed. Breathe out as your shoulders rise and in as they come down. Your body stays still; only the shoulder blades move.
Range of motion and hold
Begin every rep from a full hang, with your shoulders pulled down by the bar. Then lift them straight up, as if you wanted to touch your ears with them, and hold the top for a moment. Lower under control until they hang again. If you cannot hold the top for a moment on every rep, the weight is too heavy. Short, fast reps let you move more weight but take away the part of the movement the traps work through.
Arms, elbows and head position
Your arms are only the hooks that connect you to the bar, so keep the elbows straight and the grip firm. Look straight ahead with your neck long. Pulling the head forward or tilting it back does not raise the shoulders any higher.
Barbell in front or behind
Most lifters hold the bar in front of the thighs. Holding it behind you, just under your glutes, is a variation that keeps the bar off your thighs; train it the same way, straight up and straight down.
Muscles worked by the barbell shrug
- Primary
- Traps
- Secondary
- Neck
- Forearms
The upper traps do most of the work: they run from the base of your skull and neck to your collarbones and shoulder blades and lift the shoulders straight up. The levator scapulae at the side of your neck helps them. Your forearms hold the bar for the whole set, which is why grip often tires first. The middle and lower traps help steady the shoulder blades; in an EMG study, a shrug with the arms held slightly out to the sides raised upper and lower trap activity compared with the standard version.
Common barbell shrug mistakes
Rolling the shoulders
Circling the shoulders forward or back adds no work for the traps, which lift the shoulder blades straight up. Move straight up and straight down.
Bending the elbows
When the arms start to pull, the bar rises a little further without the traps doing more. Keep your arms long, like hooks holding the bar.
Loading too heavy for the range
Too much weight turns each rep into a short twitch. Lift as high as you can toward your ears and lower until your shoulders hang fully; take weight off if you cannot.
Pushing the head forward
Jutting the chin out at the top changes your neck position, not your shoulder height. Keep your eyes ahead and your neck long.
Bouncing with the legs
A knee dip that heaves the bar up turns the shrug into a different lift. Keep your knees still and let only the shoulders move.
Shrug tips from the Muscla training logic
- Muscla's plans leave shrugs out: the weekly set count targets eight main muscles, and the upper traps are not one of them. If you want them, add shrugs at the end of a session in your own routine and choose their progression there, for example Double progression.
- End each set with about one rep in reserve, two if you are new to training. That is Muscla's target for isolation exercises.
- Rest 75 seconds between sets when you train for muscle, 90 seconds for strength and 60 seconds for other goals.
- Earn more weight with reps. Once every set reaches the top of your range, Double progression adds 5 kg (10 lb) unless you set your own step, and the reps start again at the bottom.
- Use lifting straps once your grip gives out before your traps. Straps let the set end when your traps are tired, not your hands.
Barbell shrug sets and reps by goal
| Goal | Reps | Rest |
|---|---|---|
| Strength | 8–12 | 90 s |
| Muscle | 10–15 | 75 s |
| Lose fat | 10–15 | 60 s |
| Fit | 10–15 | 60 s |
| Comeback | 10–15 | 60 s |
These are the ranges Muscla's plan uses for this kind of exercise; in your own routine, you pick your range.
Muscla's training logic counts the barbell shrug as an isolation exercise, so the table shows the isolation ranges Muscla's plan uses, with higher reps and shorter rests than for presses and rows; pick the one for your goal for your own routine. There, Double progression lowers the weight by about 10% after three sessions without progress.

Barbell shrug questions
What muscles do barbell shrugs work?
Mainly the upper trapezius, which lifts your shoulders, helped by the levator scapulae at the side of your neck. Your forearms work hard to hold the bar.
Should I roll my shoulders when I shrug?
No. The upper traps lift the shoulder blades straight up, so rolling adds movement without adding work for them. Lift straight up, hold briefly and lower straight down.
Are barbell or dumbbell shrugs better?
Both train the upper traps. Dumbbells at your sides keep the weight from rubbing your thighs. In an EMG study, a shrug with the arms raised slightly out to the sides drew more activity from the upper and lower traps than the standard shrug.
Can I do shrugs with a trap bar or on a Smith machine?
Yes. The movement stays the same: shoulders straight up, a short hold, straight down. A trap bar keeps the weight at your sides, a Smith machine keeps the bar on a fixed path; pick one and stay with it, so your numbers stay comparable.
How heavy should barbell shrugs be?
Heavy enough that the last reps are hard, but only as heavy as you can lift high toward your ears and hold for a moment. Light loads build muscle about as well as heavy ones when sets are taken to or very near failure, so a full range comes first.
When should I do shrugs in my workout?
Add them at the end of the days you train your back. Keep them after your rows and pulldowns, so tired traps and a tired grip do not limit your main lifts.
