The dumbbell alternate biceps curl is an isolation arm exercise that builds the biceps brachii one side at a time, with the brachialis and brachioradialis assisting. Curling one arm while the other rests lets you focus on each side individually, even out strength imbalances, and keep strict form on every rep.

Dumbbell Alternate Biceps Curl: So führst du sie aus

  1. 1Stand tall holding a dumbbell in each hand at arm's length, with your palms facing in toward your thighs (neutral grip).
  2. 2Brace your core, keep your chest up, and pin your elbows close to your sides.
  3. 3Curl one dumbbell up, rotating your palm to face your shoulder (supinating) as the weight rises.
  4. 4Squeeze the biceps at the top with your forearm fully flexed, keeping your upper arm still.
  5. 5Lower that dumbbell under control back to the starting position, rotating your palm to face inward again.
  6. 6Repeat the curl with the opposite arm, alternating sides for each rep.
  7. 7Continue alternating until you complete your target reps on both arms, then lower the dumbbells to your sides.

Technik-Tipps

  • Keep your elbows fixed at your sides so the work stays on the biceps rather than swinging from the shoulder.
  • Use a full range of motion — extend the arm fully at the bottom and squeeze hard at the top of each rep.
  • Rotate your wrist as you curl so the palm faces up at the top; this supination recruits the biceps more strongly.
  • Keep the non-working arm relaxed and still while the other arm curls so each side gets honest, focused work.
  • Control the lowering phase for about two seconds instead of dropping the weight to maximize muscle tension.

Häufige Fehler

  • Swinging the torso or using momentum to heave the weight up, which shifts load off the biceps and risks straining the lower back.
  • Letting the elbows drift forward or flare out, which turns the curl into a partial front raise and reduces biceps tension.
  • Cutting the range of motion short by not fully straightening the arm at the bottom, leaving the biceps undertrained.
  • Skipping the wrist rotation and curling with a neutral grip throughout, which works the forearms more than the biceps.
  • Choosing a weight so heavy that form breaks down, leading to sloppy reps and uneven development between arms.

Häufig gestellte Fragen

What muscles does the dumbbell alternate biceps curl work?

It primarily targets the biceps brachii, with the brachialis and brachioradialis of the forearm assisting as synergists.

Why curl one arm at a time instead of both together?

Alternating lets you focus on each biceps individually, which helps fix side-to-side strength imbalances and keeps your form stricter than lifting both dumbbells at once.

Is the dumbbell alternate biceps curl good for beginners?

Yes. It is simple to learn, lets you start light, and the one-arm-at-a-time pace makes it easy to focus on clean technique before adding weight.

How many sets and reps should I do?

For building the biceps, 3 to 4 sets of 8 to 12 reps per arm with a controlled tempo is a solid range. Use a weight that makes the last couple of reps challenging.

Should I rotate my wrist during the curl?

Yes. Start with palms facing in and rotate them to face up as you lift. This supination engages the biceps more fully than curling with a fixed neutral grip.
