Stand with knees slightly bent and feet no more than shoulder width apart. Keeping back straight, bend slightly forward from the hips. Squeeze together (retract) shoulder blades. Hold dumbbells (palms in) at sides, with elbows bent at 90 degrees and upper arms perpendicular to the floor. In a controlled motion, raise dumbbells out to the sides until upper arms are parallel to the floor. While maintaining the controlled motion, return to starting position. Do not allow muscles to relax before next repetition.
