Dumbbell Biceps Curl with Overhead Extension on Stability Ball
Kneeling on a stability ball, one arm curls a dumbbell while the other straightens one overhead from behind the head; both arms work at once while the body balances.
How to do it
Setup
Kneeling upright on a stability ball, one dumbbell at the side, the other held behind the head with that elbow pointing up.
Steps
- Curl one bell as the other arm straightens overhead.
- Lower both together: one to the side, one behind the head.
- Swap the arms' jobs for the next set.
Common mistakes
First time on the ball holding weights: learn the kneel without them, close to support. Overhead elbow flaring out: keep it beside the head, pointing up. Arms moving at different speeds: start and finish both together.
Breathing
Exhale as both arms work, inhale as they return.
