 Looking high will lower your right shoulder, set most of your weight on your right side, and will encourage a shallow swing path directing the shot towards the spot you picked. To hit the ball low, look at a low spot along your intended line of flight. This will set your shoulders nearly level and place more weight on your left side, promoting a steeper angle of attack. You'll trap the ball in impact with a de-lofted club face, producing a low trajectory.
