Adjust the incline bench to a 45-degree angle. Sit on the bench with your back against the pad and feet flat on the ground. Hold a dumbbell in one hand with an overhand grip, resting it on your shoulder. Push the dumbbell up and away from your body, extending your arm fully. Pause for a moment at the top, then slowly lower the dumbbell back down to the starting position. Repeat for the desired number of repetitions, then switch to the other arm.
