How to do it
With the load in your hands, shrug the shoulders straight up toward the ears for the upper traps, without rolling them back. Pause at the top for a beat and lower under control to a stretch.
Muscles worked
Main muscle: traps. When it plans weekly volume, every set of this exercise counts in full for traps: the generator does not split it with other muscles.
Barbell shrugs or dumbbells: which one lets you load more
The classic version of the shrug uses a barbell, and it is the one that lets you move the most weight. Both hands hold the same bar in front of your body with a fixed grip, and the load is split evenly, so you do not have to stabilize two separate weights. Compared with dumbbell shrugs, the bar brushes your thighs and slightly limits the path, but in return you can load far more. The movement is the same vertical one, but the room for progression is bigger when your equipment allows it.
Choose it if you want strength and size in your upper traps and have access to a rack. It fits at the end of a pulling session, after deadlifts or rows, because the traps are already warmed up, or at the start of an upper-back day. With heavy loads your grip usually fails before the muscle does: use a mixed grip or straps so the trapezius stays the limiting factor. If the bar bothers you as it passes your legs, widen your hands a little.
A detail specific to this version: start from the rack pins at hip height or from a deadlift position, without rounding your back to lift it off the floor. Add weight when you finish all your sets comfortably at 8 to 12 reps.

Recommended sets and reps
As an isolation exercise, it works best in 3–4 sets of 10–15 reps with 0–2 RIR. Use it at the end of the session to add volume without systemic fatigue.
Common mistakes to avoid
- Rolling the shoulders in a circle when shrugging: the effective movement is vertical, straight up and down.
- Gripping the bar with each hand at a different distance from the center: one side works harder without you noticing.
- Using too much weight at the cost of technique and full range of motion.
What the research says
As an isolation move, it is mostly a way to add volume to one muscle. Gentil and colleagues (2013) found that, in beginners, adding it to a multi-joint exercise gave no extra arm growth; it pays off later on, or for muscles the compounds barely reach.
On how hard to push: the meta-analysis by Refalo and colleagues (2023) found no clear advantage in going to failure over stopping just short of it. That is why the generator programs it with reps in reserve (RIR) instead of asking for failure on every set.

How Barbell shrugs compares with other traps exercises
Of the 9 traps exercises in the catalogue, ranked from least to most fatiguing by the values the generator uses, Barbell shrugs is number 6 (tied with one other).
It sits in the middle of its group: it works as the day's main exercise or as a second or third one.
With different equipment, the same movement pattern offers 5 alternatives, such as Band Y-raise, Band shrug and Low cable shrug.
| Exercise | Equipment | Fatigue | Technique |
|---|---|---|---|
| Band Y-raise | resistance band | Low (0.4 out of 2.2) | Basic |
| Band shrug | resistance band | Low (0.5 out of 2.2) | Basic |
| Low cable shrug | cable | Low (0.6 out of 2.2) | Basic |
| Machine shrug | machine | Low (0.6 out of 2.2) | Basic |
| Dumbbell shrugs | dumbbells | Moderate (0.7 out of 2.2) | Basic |
| Barbell shrugs | barbell | Moderate (0.7 out of 2.2) | Basic |
An isolation exercise. In the trial by Gentil et al. (2015), with untrained young men over ten weeks, the biceps curl and the lat pulldown were equally effective for gaining strength and size in the elbow flexors: isolation is not filler.

Frequently asked questions
What muscles does Barbell shrugs work?
Barbell shrugs mainly works the traps muscle group, plus synergist and stabilizer muscles depending on the variation.
How many sets of Barbell shrugs should I do?
Between 3 and 5 sets per session, adjusting the total weekly volume for traps to your level (about 10–20 sets per muscle per week).
Are barbell shrugs better than dumbbell shrugs?
The barbell lets you load more and suits you if you want to progress in weight, but you have to pass it in front of your thighs and it limits shoulder freedom a bit. Dumbbells leave your arms at your sides and often feel more natural. Many lifters alternate both depending on the day and the equipment available.
