Band Bicep Curls

The band bicep curl is a curl where you stand on a resistance band and pull the ends up toward your shoulders with an underhand grip. The band gets harder as it stretches, so the top of the rep is the hardest part, making it a portable way to train the biceps at home or while travelling.

Also known as: Resistance band bicep curl, Banded bicep curl, Band curl

What muscles does the band bicep curls work?

Primary movers

  • Biceps brachii

Assisting muscles

  • Brachialis
  • Brachioradialis
  • Forearm flexors

The biceps flex the elbow against the band's resistance. Bands stretch, so the tension rises as you curl, which means the hardest point is at the top where the biceps are shortened.

That is the opposite of a dumbbell curl, where the hardest point is in the middle. Bands are a useful complement for peak contraction.

The brachialis and forearms help as usual. Keeping your wrists straight stops the forearms taking over.

Bands are cheap and portable, and you can change difficulty by choosing thicker bands, standing wider or shortening the band.
