Barbell shrug: muscles worked and how to do it

The shrug lifts your shoulders straight up toward your ears while you hold a barbell at arm's length in front of your thighs. GymTribe's library lists it as Barbell Shrug, with the traps as its target muscle.

How to do a shrug

  1. Set the bar in a rack at about mid-thigh height and grip it overhand, just outside your thighs.

  2. Lift it out and stand tall, arms straight, with the bar resting against your thighs.

  3. Lift your shoulders straight up toward your ears as high as they go, keeping your arms straight.

  4. Pause for a moment at the top.

  5. Lower your shoulders under control until your arms hang fully again.

These steps describe common technique. If something hurts, stop and ask a qualified coach or clinician.

Common shrug mistakes

  • Rolling your shoulders

    Lift straight up and down. Rolling adds nothing and makes reps harder to compare.

  • Bending your elbows

    Keep your arms straight; the movement comes from your shoulders.

  • Tiny reps with heavy weight

    Use a load you can lift through the full range, with a pause at the top.

  • Jutting your head forward

    Keep your chin level and your neck in line with your back.

How to track your shrug

Log the weight and reps of every set. Over a few weeks, the heaviest weight you lift and your estimated one-rep max show whether you are getting stronger, even when your sets use different rep counts.

Estimated 1RM, Epley formula

100 kg × (1 + 12 ÷ 30) ≈ 140 kg

A set of 12 at 100 kg estimates a one-rep max of about 140 kg.

Barbell shrug questions

What muscles do shrugs work?

The traps, mainly their upper part, with your forearms holding the bar. In GymTribe's muscle map, each set of Barbell Shrug counts toward the traps.

Barbell or dumbbell shrugs?

Dumbbells at your sides let your shoulders move straight up without the bar against your thighs. The barbell lets you load more. GymTribe lists Dumbbell Shrug as its own exercise, also counted toward the traps.

Should I use straps for shrugs?

Many people do once their grip gives out before their traps. If you start using straps, note it, because it can change how much you lift.

How do I estimate my shrug one-rep max?

Use the Epley formula, weight × (1 + reps ÷ 30). A set of 12 at 100 kg estimates about 140 kg. The 1RM calculator on this site does the sum for any set.

How do I track my shrug in GymTribe?

Log each set's weight and reps under Barbell Shrug. Every session adds a point to its charts: heaviest weight and estimated 1RM, best set volume and most reps, and best session volume and max session reps. A New PR alert appears when a set beats your heaviest weight, estimated 1RM or rep record.
