Shrug

Also known as: Barbell shrug, Dumbbell shrug

A direct trap-builder — elevating the shoulders against load.

What it is

An exercise where you elevate your shoulders straight up against a loaded barbell or dumbbells, isolating the upper trapezius. It's the main direct movement for building the upper traps.

Muscles worked

Primary: Traps (upper). Secondary: Forearms.

How to perform it

  1. Stand holding a barbell or dumbbells at arm's length, shoulders relaxed down.
  2. Brace the core and keep the arms straight throughout.
  3. Elevate the shoulders straight up toward your ears as high as possible.
  4. Pause briefly at the top, then lower under control to a full stretch.

Common form faults

  • Rolling the shoulders in circles. Shrug straight up and down — rolling adds no benefit and can irritate the shoulders.
  • Bending the elbows to help lift. Keep the arms straight so the traps, not the biceps, do the work.

Programming

A simple, effective upper-trap builder. Usually 8–15 reps with a pause at the top; a full range and controlled tempo beat bouncing heavy weight.

Frequently asked questions

Do I need to train traps directly?
Deadlifts, rows and carries already train the traps hard, so direct shrugs aren't essential. They're a useful add-on if bigger upper traps are a specific goal.
Should I roll my shoulders when shrugging?
No — shrug straight up and down. Rolling the shoulders adds no extra benefit and puts the joint in a weaker position under load.
