Dumbbell One-Arm Seated Bicep Curl on Stability Ball
One dumbbell curled while seated on a stability ball, both feet down; the single load asks the trunk to keep the ball from rolling sideways.
How to do it
Setup
Seated tall on a stability ball, feet wide, one dumbbell at the side, palm forward, free hand on the thigh.
Steps
- Curl the bell to the shoulder, elbow at your side.
- Hold the top without the ball shifting.
- Lower slowly; switch arms after the set.
Common mistakes
Tilting toward the bell: keep the shoulders level. Feet close together: set them wide. Elbow creeping forward: it stays by the ribs.
Breathing
Exhale on the curl, inhale lowering.
