Your hips should remain square to the target on all planes. You should not be twisting your hips horizontally and if your body weight is evenly distributed on both feet, then your hips should remain level on the vertical plane as well.
Your shoulders should remain upright in the stance and square to the target path on all planes. There should be no twisting vertically or horizontally here either. Your head should be erect with your eyes concentrated on the target during the entire delivery.
