The dumbbell bicep curl is versatile and effective for targeting the biceps. It allows a natural range of motion, reducing injury risk and promoting balanced muscle development in both arms.

1. Stand with your feet shoulder-width apart, holding dumbbells with an underhand grip.
2. Keep your elbows close to your sides and curl the dumbbells towards your shoulders.
3. Squeeze your biceps at the top of the movement.
4. Slowly lower the dumbbells back to the starting position.
