Resistance Band Concentration Curl

The resistance band concentration curl is an isolation exercise designed to target the biceps brachii and brachialis with minimal momentum. It suits lifters of all experience levels and is best placed at the end of an arm or pulling workout to fully fatigue the biceps without loading the spine.

Muscles: Biceps
Equipment: Resistance bands
Type: Strength
Animation: Women

How to do it

Sit on a chair or bench with your feet wider than shoulder-width and pin one end of the band to the floor under your foot.
Grasp the other end of the loop with the hand on the same side, palm facing up, and brace the back of your upper arm against your inner thigh.
As you exhale, bend your elbow and curl your hand up toward your shoulder.
Squeeze your biceps at the top of the movement.
Inhale and slowly lower your hand back to the starting position.
Complete all repetitions, then switch arms.

Common mistakes

Lifting the elbow off the inner thigh, which brings the shoulder and back muscles into play and reduces biceps isolation.
Letting the band snap back during the lowering phase, which loses the benefit of eccentric muscle tension.
Curling the wrist excessively at the top of the movement, shifting the workload onto the forearm flexors.
Using a band that is too heavy, which leads to torso swinging and an incomplete range of motion.

Tips

Adjust the resistance by stepping on the band closer to your working hand to shorten the loop.
Pause for a full second at the top of the curl to maximize the peak contraction against the band's tension.
Keep your upper arm completely vertical and stable against your thigh throughout the entire set.

Sets and reps

Perform 3 to 4 sets of 12 to 15 controlled repetitions per arm, resting 45 to 60 seconds between sides.

Questions

How does this compare to doing concentration curls with a dumbbell?

The resistance band creates variable resistance, meaning the load progressively increases as you curl upward, delivering maximum tension at peak contraction where dumbbells often become easier.

Is this exercise safe if you have lower back issues?

Because the movement is performed seated with your arm anchored against your thigh, it places virtually no axial load on the spine; stop immediately and consult a professional if you feel any back pain.
