This exercise targets the biceps and brachialis, using a neutral grip to enhance arm strength and size. The cross body motion allows for better isolation of the arm muscles.

1. Stand with your feet shoulder-width apart, holding dumbbells with a neutral grip.
2. Curl one dumbbell across your body towards the opposite shoulder.
3. Squeeze your bicep at the top of the movement.
4. Slowly lower the dumbbell back to the starting position.
5. Repeat with the other arm.
