The band hammer curl is a forearm and arm exercise that primarily targets the brachioradialis, with the biceps brachii and brachialis assisting. Using a resistance band and a neutral (thumbs-up) grip, it builds elbow-flexor strength and thicker-looking forearms while keeping the wrists in a joint-friendly position.

How to do the Band hammer curl

  1. 1Stand on the middle of the resistance band with feet about shoulder-width apart for an even, stable base.
  2. 2Hold one end of the band in each hand with a neutral grip — palms facing each other, thumbs pointing up.
  3. 3Let your arms hang straight down at your sides with your elbows pinned close to your torso.
  4. 4Brace your core and keep your shoulders back, then curl both hands up toward your shoulders, keeping your palms facing inward throughout.
  5. 5Squeeze the forearms and biceps at the top, keeping your wrists straight and elbows still.
  6. 6Lower the hands under control back to the starting position, resisting the band's pull rather than letting it snap down.
  7. 7Complete your reps, then step off the band carefully to release the tension.

Form tips

  • Keep your elbows fixed at your sides — the movement should happen only at the elbow joint, not by swinging the upper arms.
  • Maintain the neutral grip from start to finish; rotating the wrists turns it into a standard curl and shifts work off the brachioradialis.
  • Control the lowering phase for two to three seconds to keep tension on the muscles where the band is weakest.
  • Adjust resistance by widening your stance or choking up on the band so the top of each rep is challenging but clean.

Common mistakes

  • Swinging the torso or shoulders to fling the hands up, which uses momentum instead of the forearms and biceps and reduces the training effect.
  • Letting the band snap back down quickly, wasting the eccentric portion of the rep where much of the growth happens.
  • Letting the elbows drift forward or flare out, which recruits the shoulders and takes tension off the target muscles.
  • Bending the wrists toward you at the top, which strains the wrist joint and breaks the neutral hammer position.

Frequently asked questions

What muscles does the band hammer curl work?

It primarily targets the brachioradialis in the forearm, with the biceps brachii and brachialis assisting. The neutral grip emphasizes the forearm and the outer arm more than a standard supinated curl.

How is the hammer curl different from a regular curl?

The hammer curl uses a neutral grip with palms facing each other, which shifts more work onto the brachioradialis and brachialis. A regular curl turns the palms up, placing more emphasis on the biceps brachii.

Is the band hammer curl good for beginners?

Yes. The band provides smooth, scalable resistance and is easy on the joints, so beginners can learn elbow-flexor control safely and adjust the difficulty just by changing their stance or grip on the band.

How many sets and reps should I do?

For most lifters, 3 to 4 sets of 10 to 15 reps works well. Bands keep tension high through the range, so focus on a controlled tempo and a full squeeze rather than chasing heavy resistance.
