Rails that carry the bar's balance let you shrug straight up with zero drift, and the hooks let you rack the weight instantly at any height - useful when pushing sets close to failure. You give up the stabilizer work of a free bar, a fair trade when pure trap loading is the goal.

How to do the Smith Machine Shrug

  1. Stand with your feet shoulder-width apart and your knees slightly bent.
  2. Grasp the barbell with an overhand grip, hands slightly wider than shoulder-width apart.
  3. Keep your arms straight and your shoulders relaxed.
  4. Lift your shoulders up towards your ears, squeezing your traps at the top.
  5. Hold for a moment, then slowly lower your shoulders back down to the starting position.
  6. Repeat for the desired number of repetitions.

Tip: Hold the top for two seconds and lower for three.

Muscles worked

Primary

Traps · Back

The upper traps lift the shoulder blades straight up and should be squeezed hard at the top of each rep, with the burn sitting between the neck and the shoulders.

Secondary

Common mistakes

  • Rolling the shoulders — a circular motion does nothing extra and irritates the shoulder; move straight up and straight down.
  • Bouncing out of the bottom — let the shoulders drop fully at the bottom, pause, then shrug up from a dead stop.
  • Pulling the head forward — keep the chin tucked and the head neutral, since jutting the head forward shortens the range.
  • Too heavy to squeeze — if you cannot hold the top for a full count, the weight is too heavy for the traps to actually contract.

Where it fits in a workout

Shrugs go at the end of a back or shoulder session after the pressing and rowing. Superset them with a face pull or a rear delt fly on the same station.

When to talk to someone

  • Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
  • Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
  • Pregnant: ask your obstetric care provider which exercise suits you.
