The Smith machine bicep curl is a standing curl variation that uses the machine's fixed vertical bar path to add stability, letting you focus entirely on elbow flexion. It primarily targets the biceps brachii, with the brachialis and brachioradialis assisting throughout the movement.

Smith Machine Bicep Curl: So führst du sie aus

  1. 1Set the Smith machine bar to hip height. Stand facing the bar with your feet shoulder-width apart.
  2. 2Take an underhand (supinated) grip on the bar, hands slightly inside shoulder-width, and unrack it by rotating the bar off the safety hooks.
  3. 3Let the bar hang at arm's length in front of your thighs with your elbows tucked close to your sides — this is your starting position.
  4. 4Brace your core and keep your chest tall.
  5. 5Curl the bar upward by flexing your elbows, keeping your upper arms as still as possible and your elbows close to your sides.
  6. 6Continue curling until your biceps are fully contracted and the bar is near shoulder height.
  7. 7Squeeze your biceps at the top for a brief pause.
  8. 8Lower the bar slowly and under control back to the starting position, fully extending your elbows to complete the rep.
  9. 9After your final rep, re-rack the bar by rotating it onto the safety hooks.

Technik-Tipps

  • Stand with your thighs almost touching the bar. Because the path is locked vertical, standing too far back forces your elbows forward early and shortens the range you can actually load.
  • Keep your wrists straight and stacked over your forearms instead of letting the bar roll back into your fingers — a broken wrist angle bleeds force before it reaches the biceps.
  • Keep your shoulders down and back; if they start to shrug or roll forward, the weight is too heavy for strict elbow flexion.
  • Exhale as you curl and inhale as you lower, and because you can twist the bar onto the hooks at any point in the range, you can safely take a set close to failure without a spotter.

Häufige Fehler

  • Swinging the torso backward to help lift the bar, which shifts work away from the biceps brachii and onto the lower back.
  • Letting the elbows drift forward as the bar rises, which reduces peak contraction and offloads tension from the biceps.
  • Rushing the lowering (eccentric) phase — the slow return is where significant muscle stimulus occurs, so skipping it wastes the rep.
  • Using a grip that is too wide for the fixed bar path, which forces the wrists into an unnatural angle and strains the joints.

Häufig gestellte Fragen

What muscles does the Smith machine bicep curl work?

It primarily targets the biceps brachii, with the brachialis and brachioradialis acting as synergists to assist with elbow flexion.

Is the Smith machine bicep curl better than a free-weight barbell curl?

Neither is strictly better. The fixed bar path removes the need to balance the bar, letting you focus entirely on elbow flexion — useful for beginners or when training to failure without a spotter. Free-weight curls require more stabilisation from supporting muscles.

What grip width should I use?

Slightly inside shoulder-width works well for most people. This keeps the wrists neutral and aligns comfortably with the bar's fixed vertical path.

How high should I set the bar before starting?

Set the bar so it sits at roughly hip height when the hooks are engaged. This lets you unrack and re-rack smoothly without bending down or reaching up.
