Dumbbell One-Arm Triceps Extension on Stability Ball
The seated one-arm overhead extension sitting on a stability ball instead of a bench, the free hand on the hip; the ball asks the trunk to stay tall.
How to do it
Setup
Seated tall on a stability ball, feet wide, one bell overhead, the free hand on the hip.
Steps
- Lower the bell behind the head by bending the elbow.
- Keep the elbow pointing up and the ball still.
- Extend to a straight arm; switch sides after the set.
Common mistakes
Rolling on the ball as the bell drops: plant the feet wide and brace. Elbow flaring out: keep it by the ear. Leaning to the working side: sit tall and square.
Breathing
Inhale lowering, exhale extending.
