Dumbbell Decline Skullcrusher

Start by lying on a decline bench with a dumbbell in each hand. Hold the dumbbells above your chest with your arms extended and your palms facing each other. This is the starting position. Slowly lower the dumbbells towards your forehead by bending your elbows. Keep your upper arms stationary and only move your forearms. Once the dumbbells are close to your forehead, reverse the motion by extending your elbows and returning to the starting position.
