Lean:

If you think Lean is your best approach, then you should focus on eliminating muda in your swing. Do not try to “push” the club head towards the ball but rather let a synchronized body turn to naturally “pull” the club head in order to achieve a smooth flow of your swing. The game of golf is a process of relentless continuous improvement. We do not generally recommend you to invest too much energy to your tools because dependence on such frequently undermines the development of the correct mindset. If you focus on improving every little piece, your efforts will eventually show up in your score and hence your handicap, which should not be your ends but means to the way of golf.
