Common mistakes

Lifting through the shoulders

Do not move your upper arms forward as the dumbbells rise; create the curl range through elbow flexion.

Thrusting the hips

Do not launch the loads from the bottom with your pelvis; keep your torso stable.

Curling the wrists

Do not finish the top by bending your hands toward your palms; keep the handles aligned with your forearms.

Short bottom range

Do not leave your arms progressively more bent each repetition; return to comfortable, controlled extension.

Asymmetric repetitions

Do not raise or lower one dumbbell before the other; maintain simultaneous curl rhythm.

Hitting at the top

Do not stop the weights by striking your shoulders; decelerate with control at the end of the contraction.
