According to SkyTrak Golf Australia, to improve your swing, you’ve to fix your faults. But first, you have to be able to analyse and diagnose what you’re doing wrong. You probably want to avoid the mistakes by working on the fundamentals like grip, setup, tempo.
There are lots of aspects to playing golf; short game, strategy, equipment. But it comes down to hitting the ball. If your shots aren’t better, your scores won’t be either. So to me you’ve to hit better shots to break the scoring barriers.
But that’s difficult to do if you don’t know what you need to fix. You need a plan and the simplest approach is to look at your ball flight. A good plan starts with the question “What is my ball doing?” If you’re slicing, there are only so many things that cause a slice. So you find what causes the slice and fix it.
