A seated arm-strengthening exercise performed on an exercise ball where you alternate curling dumbbells one arm at a time. Sit with your core braced and feet planted for stability, then lift one dumbbell by bending the elbow while keeping your torso steady. Lower with control and switch to the other arm. The unstable surface of the ball increases core engagement and balance demands while isolating each biceps muscle for focused strength and growth.
