barbell rear delt raise

Stand with your feet shoulder-width apart and hold a barbell with an overhand grip, palms facing down. Bend your knees slightly and hinge forward at the hips, keeping your back straight. Raise the barbell out to the sides, keeping your arms straight, until they are parallel to the ground. Pause for a moment at the top, then slowly lower the barbell back to the starting position. Repeat for the desired number of repetitions.
