Dumbbell Seated Biceps Curl (On Stability Ball)
Both dumbbells curled while sitting on a stability ball; the unstable seat makes the trunk hold the posture through the whole set.
How to do it
Setup
Seated tall on a stability ball, feet flat and hip-width, bells at the sides, palms forward.
Steps
- Curl both bells to the shoulders without rocking on the ball.
- Keep the feet planted and the back upright.
- Lower slowly to straight arms.
Common mistakes
Feet close together on a wobbly ball: set them hip-width or wider for a stable base. Rolling back on the ball to help the lift: the hips stay still. Slumping as the set goes on: sit tall on top of the ball.
Breathing
Exhale on the curl, inhale lowering.
