How can I effectively perform the bench shoulder press exercise to target my shoulder muscles?

To effectively perform the bench shoulder press exercise to target your shoulder muscles, lie on a flat bench with your feet flat on the floor. Hold a barbell with an overhand grip, slightly wider than shoulder-width apart. Lower the barbell to your chest, then push it back up to the starting position, fully extending your arms. Keep your core engaged and focus on using your shoulder muscles to lift the weight. Repeat for the desired number of repetitions.
