How can I effectively perform standing dumbbell raises to target my shoulder muscles?

To effectively perform standing dumbbell raises to target your shoulder muscles, stand with your feet shoulder-width apart, hold a dumbbell in each hand with palms facing your body, and lift the weights straight out to the sides until your arms are parallel to the floor. Lower the weights back down slowly and repeat for desired reps. Focus on controlled movements and proper form to engage your shoulder muscles effectively.
