Band Hammer Curl: how to do it right
In short: The resistance band hammer curl isolates the biceps and especially the brachialis, with tension peaking at mid-range thanks to the band's increasing resistance.
How to do it, step by step
- 1Standing, foot on the band, neutral hammer grip, elbows tight against the torso and fixed.
- 2Bend the elbows, raising your hands toward your shoulders without swinging your body.
- 3Go for the full range but stay continuous, with no jerk or dead time at the top.
- 4Brake the return toward the bottom by controlling the band, don't let it pull you.
- 5Keep the wrist neutral and rigid from start to finish, no breaking.
The mistake to avoid
Don't let your wrists break. Keep your forearm neutral throughout.
Other common mistakes
- You swing the torso to throw the load up: lock your abs and keep the elbows still against the trunk.
- You let the band bring you back too fast: actively brake the return phase to keep some eccentric work.
- The wrist breaks and turns toward supination: keep the hammer grip strict to target the brachialis.
- You only curl up to half height: go for the high range where the band tension is the strongest.
Muscles worked
- Main:
- Biceps
- Supporting:
- Forearms
The brachialis (under the biceps) is the prime mover thanks to the neutral grip, palms facing inward, it pushes the biceps upward and thickens the arm. The biceps brachii (especially the long head) takes part in the elbow flexion. The brachioradialis and the forearms stabilize the neutral wrist continuously.

Frequently asked questions
How do I do this exercise?
Standing, foot on the band, neutral grip with palms facing each other, elbows tight against the torso and fixed. Bend the elbows, raising your hands toward your shoulders without swinging, then brake the return by controlling the band.
How far up do I curl?
Go for the full high range, that's where the band pulls the hardest. At the bottom, lower until your arms are almost straight while keeping the tension.
I don't feel anything, is that normal?
You should feel the underside of the biceps and the top of the forearm. Feeling the forearm work is normal here, it's even the goal: the neutral grip targets the muscle that pushes the biceps upward and thickens the arm.
How fast should I do the movement?
Fluid and continuous, with no dead time at the top. Never go slack in the middle zone: that's where the elbow angle and the band tension combine best.
How do I position myself?
Foot well centered on the band, so that you already have a slight tension with arms straight. Without this pre-tension, the muscle rests between each rep and you lose half the work.
