Shrugs: the go-to exercise for building traps
Shrugs come down to one simple move: you lift your shoulders towards your ears, then lower them slowly. Nothing else isolates the upper back like it. In the gym it stays the reliable choice for thickening the neck area and widening your silhouette from the front. Most coaches slot it in at the end of a back or shoulder session.
Shrug meaning: what the name tells you
The shrug meaning is right there in the word: you shrug your shoulders, the same way you would in conversation. It comes from the verb to shrug. And that image is the whole cue for shrug form: a short vertical lift, no rolling, no swinging. One shrug equals one full rep.
Which muscles do shrugs work?
The upper fibres of the trapezius do most of the work. The levator scapulae and the rhomboids chip in. People often call them trap shrugs because that muscle dominates the movement so completely. Your forearms take the load too: grip is usually the first thing to give out.
The variations worth knowing
Dumbbell shrugs
Dumbbell shrugs let your arms hang free at your sides. The range of motion is wide and the wrist stays neutral. Shrugs with dumbbells are a perfect starting point for beginners.
Barbell shrugs
Barbell shrugs let you load up more weight. Hold the bar in front of your thighs and keep your arms straight. A trap bar makes shoulder positioning even easier.
Machine shrugs
Machine shrugs guide the path from start to finish. A solid option for finishing with long sets, with no balance to manage.
Should you go heavy?
Plenty of lifters go too heavy and cut the range of motion down to an inch. Heavy shrugs still have their place, but only if the movement stays full. Aim for 8 to 15 reps with a one-second pause at the top. Straps help when your grip gives out before your traps do.
Common mistakes
- Rolling the shoulders: you stress the joint for nothing.
- Bending the elbows and turning the move into a row.
- Sinking your head into your shoulders instead of keeping the neck long.
Letting the weight drop back down without control.

Two sessions a week is enough to keep making progress on shrugs.
Do shrugs make your neck bigger?
