Stand upright holding a barbell with an overhand grip, arms hanging down. With a slight hinge at the hips and a stable core, lift the barbell outward and up toward shoulder level by moving your arms to the sides, focusing on contracting the rear deltoids. Pause briefly at the top, then lower the barbell back down in a slow, controlled motion. Keep tension on the target muscles and avoid swinging or using momentum.
