The dumbbell biceps curl with arm blaster is an isolation exercise that targets the biceps brachii, with the brachialis and brachioradialis assisting. The arm blaster is a curved plate worn against your torso on a neck strap that braces your upper arms and elbows, removing body swing so each rep loads the biceps directly. It is a strength movement for building arm size and a stricter curl.

Dumbbell Biceps Curl (with arm blaster): So führst du sie aus

  1. 1Hang the arm blaster from your neck strap and rest the curved plate against your upper abdomen, then settle your upper arms and the backs of your elbows flat against it.
  2. 2Pick up a dumbbell in each hand and let your arms hang straight down, palms facing forward (supinated) at the bottom.
  3. 3Brace your core and keep your elbows pinned to the arm blaster throughout the set so only your forearms move.
  4. 4Curl both dumbbells upward by contracting your biceps, keeping your wrists straight and your upper arms locked against the plate.
  5. 5Squeeze the biceps hard at the top when the dumbbells reach shoulder height.
  6. 6Lower the dumbbells under control back to the fully extended starting position, resisting the weight on the way down.
  7. 7Complete your reps, then set the dumbbells down and remove the arm blaster from your neck.

Technik-Tipps

  • Keep the backs of your elbows in constant contact with the arm blaster pad — that contact is what makes this curl strict, so don't let the elbows drift off it.
  • Use a deliberate tempo, taking 2–3 seconds to lower each rep, since the arm blaster removes momentum and rewards controlled eccentrics.
  • Fully supinate your wrists at the top so the biceps reach peak contraction.
  • Adjust the neck strap so the plate sits comfortably against your torso; a strap that is too long lets your elbows slide and defeats the purpose.

Häufige Fehler

  • Swinging the torso or using the hips to heave the weight up, which the arm blaster is specifically designed to prevent — if you feel yourself swaying, the load is too heavy.
  • Letting the elbows lift off the arm blaster plate, which turns the strict curl into a front-raise-like cheat and shifts work away from the biceps.
  • Bending the wrists backward as you curl, which strains the wrist and bleeds tension out of the biceps.
  • Using too much weight and only doing partial reps, cutting the range of motion short and reducing the muscle stimulus.
  • Dropping the dumbbells quickly on the way down, wasting the eccentric phase where much of the muscle-building tension lives.

Häufig gestellte Fragen

What muscles does the dumbbell biceps curl with arm blaster work?

It primarily works the biceps brachii, with the brachialis and brachioradialis of the forearm assisting. Bracing the elbows against the arm blaster isolates the biceps more than a standard standing curl.

What does an arm blaster actually do?

An arm blaster is a curved metal or aluminum plate worn against your torso on a neck strap. It braces your upper arms and elbows in a fixed position, eliminating body swing so the biceps do the work instead of momentum.

Is the arm blaster curl good for beginners?

Yes. Because it locks your elbows in place and removes cheating, it teaches strict curl form and is a good way for newer lifters to learn to isolate the biceps.

How many sets and reps should I do?

For arm size, 3–4 sets of 8–12 reps with a weight you can control through a full range works well. Since the arm blaster removes momentum, use a lighter dumbbell than you would for a swinging curl.

Arm blaster curl vs standing dumbbell curl — what's the difference?

A standing curl lets the elbows and torso move, so some lifters use body english to move more weight. The arm blaster pins the elbows and torso, forcing stricter reps that target the biceps more directly with less load.
