The reverse grip dumbbell bicep curl targets the biceps and forearms using an overhand grip, promoting balanced muscle development and improved grip strength. This exercise helps to enhance the brachialis muscle, adding size and strength to the arms.

1. Stand with your feet shoulder-width apart, holding dumbbells with an overhand 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.
