Smith Shrug: How to Do It & Muscles Worked

The smith shrug is an exercise performed on a Smith machine to target the trapezius muscles. It involves lifting the shoulders towards the ears while holding a barbell, focusing on squeezing the traps at the top of the movement.

How to do the smith shrug

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

Sets, reps and programming

Suggested sets, reps and rest for the smith shrug by training goal
Goal Sets Reps Rest Effort
Strength 3–5 3–6 3–5 min 1–3 reps in reserve
Muscle growth 3–4 6–12 2–3 min 1–2 reps in reserve
Muscular endurance 2–3 12–20 1–2 min 1–3 reps in reserve

Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
