The dumbbell standing one arm concentration curl is a single-arm isolation exercise that primarily targets the brachialis, with the biceps brachii and brachioradialis assisting. Performed bent forward at the hip with one arm hanging free, it strips away momentum so you build strength and thickness in the upper arm one side at a time.

Cómo hacer el Dumbbell Standing One Arm Concentration Curl

  1. 1Hold a dumbbell in one hand and stand with your feet roughly shoulder-width apart, knees slightly bent.
  2. 2Hinge forward at your hips so your torso is angled toward the floor, letting the working arm hang straight down.
  3. 3Brace your free hand on your thigh or a nearby bench for support and keep your back flat.
  4. 4With your palm facing forward, curl the dumbbell up toward your shoulder by bending only at the elbow.
  5. 5Keep your upper arm still and squeeze the muscle hard at the top of the curl.
  6. 6Lower the dumbbell under control until your arm is fully extended again.
  7. 7Complete all reps on one arm, then switch the dumbbell to the other hand and repeat.

Consejos de técnica

  • Pin your upper arm in place so the elbow doesn't drift forward or back — isolating the joint keeps tension on the brachialis and biceps.
  • Lower the weight slowly over 2–3 seconds; the lengthening phase drives much of the strength and size gains.
  • Keep your wrist neutral and firm rather than letting it bend back under the load.
  • Pick a weight light enough that you can finish each rep without swinging your torso to help.

Errores comunes

  • Swinging the torso or jerking the dumbbell up, which uses momentum instead of the arm and reduces the work on the target muscle.
  • Letting the upper arm swing forward as you curl, which shifts effort to the shoulder and shortens the range the elbow flexors do.
  • Cutting the descent short or dropping the weight, which skips the most productive part of the rep and risks elbow strain.
  • Rounding the lower back while hinged forward, which puts unnecessary stress on the spine.

Preguntas frecuentes

What muscles does the dumbbell standing one arm concentration curl work?

It primarily targets the brachialis, the muscle beneath the biceps that adds thickness to the upper arm, with the biceps brachii and brachioradialis assisting.

How is this different from the seated concentration curl?

Both isolate one arm, but here you stay standing and hinge forward at the hip rather than sitting with your elbow braced on your inner thigh. The standing version frees the arm to hang and relies on your support hand and bracing for stability.

How many sets and reps should I do?

For arm size and definition, 3 sets of 10–15 reps per arm with a controlled tempo works well. Use a weight that makes the last couple of reps challenging without swinging.

Why does the standing concentration curl emphasize the brachialis?

Curling with a forward-facing palm and a strict, pinned elbow keeps the brachialis heavily loaded throughout, while the biceps brachii and brachioradialis assist the movement.
