    1. Sit down on a flat bench with one dumbbell in front of you between your legs. Your legs should be spread with your knees bent and feet on the floor.

    3. While holding the upper arm stationary, curl the weights forward while contracting the biceps as you breathe out. Only the forearms should move. Continue the movement until your biceps are fully contracted and the dumbbells are at shoulder level.

Dumbbell One Arm Concentration Curl (On Stability Ball) FAQ

What muscles does Dumbbell One Arm Concentration Curl (on Stability Ball) work?

It primarily targets the biceps brachii and brachialis through elbow flexion, with secondary activation of the brachioradialis. The stability ball increases core and scapular stabilizer demand, so you also recruit obliques and erector spinae to maintain posture.
