Dumbbell Hammer Curl on Stability Ball
The hammer curl seated on a stability ball: both bells rise thumbs up while the ball keeps the trunk working to stay balanced.
How to do it
Setup
Seated tall on a stability ball, feet wide, dumbbells at the sides in a neutral grip.
Steps
- Curl both bells to the shoulders, thumbs up.
- Keep the palms facing each other throughout.
- Lower slowly without rolling on the ball.
Common mistakes
Palms rolling up as the bells rise: the thumbs stay on top. Ball rolling back on the way up: plant the feet and brace. Slumping as the set goes on: sit tall on the ball's top.
Breathing
Exhale on the curl, inhale lowering.
