Set up an incline bench at a 45-degree angle. Sit on the bench with your feet flat on the ground and your back pressed firmly against the bench. Hold a dumbbell in each hand, palms facing forward, and lift them to shoulder height. Slowly lower the dumbbells to the sides of your chest, keeping your elbows at a 90-degree angle. Push the dumbbells back up to the starting position, fully extending your arms. Repeat for the desired number of repetitions.
