How to perform the Resistance Band Curl
- Stand on the middle of a resistance band with both feet and hold an end in each hand with a supinated grip.
- A band gives ascending resistance: it is easiest at the bottom and hardest at the fully contracted top, opposite to a dumbbell.
- Pin the elbows to the sides and curl the handles up by flexing the elbows against the increasing band tension.
- Because resistance peaks at the top, squeeze the fully shortened contraction hard where the band pulls back the most.
- Lower under control, resisting the band as it tries to snap the arms back to extension.
- Keep tension on the band at the bottom by not letting it go fully slack between reps.
Suggested working range: 12–20 reps. Default progression: double progression.
Common mistakes
- •Letting the band go fully slack at the bottom so tension is lost between reps.
- •Failing to squeeze the top where the band resistance is actually greatest.
- •Letting the band snap the arms back down instead of controlling the eccentric.
- •Swinging the torso to help against the increasing band tension near the top.
