How to perform Calf-Machine Shoulder Shrug

  1. Position yourself on the calf machine so that the shoulder pads are above your shoulders. Your torso should be straight with the arms extended normally by your side. This will be your starting position.
  2. Raise your shoulders up towards your ears as you exhale and hold the contraction for a full second.
  3. Slowly return to the starting position as you inhale.
  4. Repeat for the recommended amount of repetitions.

Muscles worked

  • Back (primary): pulls the arms down and toward the torso and keeps the spine stable.

Sets & reps by goal

GoalSets × repsLoadRest
Strength3–5 × 3–5Heavy (~85%+)2–3 min
Hypertrophy3–4 × 8–12Moderate (~65–75%)60–90 s
Endurance2–3 × 15–20Lighter (~50–60%)30–45 s

Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.

Form tips

  • Start each rep by pulling the shoulder blades in first, then drive with the elbows — think of pulling with the elbows, not the hands.
  • Set the seat and pads so the machine's pivot lines up with the joint you're training before your first rep.
  • Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
  • Control the lowering phase — a 2–3 second descent builds more than dropping the weight.

Common mistakes

  • Yanking with the arms and forgetting the back, so the biceps give out before the target muscle does.
  • Leaving the seat or range on a setting that forces the joint into an awkward angle.
  • Chasing weight jumps before the current load feels solid on every rep.
