Tiger’s posture is exemplary now. In the past, his set-up has often lacked definition and he has stood too upright at address. Here he is leaning forwards a little more from his hips and, as a result, his upper body is more inclined. The angle from the top of his head to his tailbone is neutral, he has the perfect amount of knee flex and his weight is centred on his feet.

In the past, Tiger has been guilty of setting a little too much weight towards his heels at address. He has rectified this flaw here. His weight is now perfectly balanced between his heels and toes.
