Stand up, feet shoulder width apart, knees slightly bent, bend your torso forward and kept it at a 45-degree angle with the floor. Pull the barbell to the sternum while flexing your elbows and pulling your shoulder blades in toward your spine then get back to the initial position.
You can also perform the exercise in a reverse grip by following the same principles. Another option is to hold the barbell in a reverse close-grip manner so you focus more on the outer parts of your upper back. Make sure your back is kept straight throughout the movement.
