Set up an incline bench at a 45-degree angle. Sit on the bench with your back against the pad and feet flat on the ground. Hold a barbell with an overhand grip, slightly wider than shoulder-width apart. Lift the barbell up to shoulder height, keeping your elbows slightly bent. Slowly raise the barbell overhead, extending your arms fully. Pause for a moment at the top, then slowly lower the barbell back to shoulder height. Repeat for the desired number of repetitions.
