A stability-enhanced biceps curl performed while seated on an exercise ball with one leg lifted to challenge balance. Sit upright on the ball holding dumbbells at your sides, lift one leg off the floor, and curl the weight up by bending your elbows while keeping your upper arms still. Lower with control and switch legs after your set. This variation increases core engagement and balance demands while targeting the biceps.
