A good impact position requires solid fundamentals at address.
I will take you through the basics of the grip, address, alignment and ball position. You should be aware that any errors in the fundamentals will seriously affect your chances of improving your golf swing.
Do not neglect any element of these four basic components. They are the building blocks for your future as a golfer.
It is unfortunate in golf that the most important areas of the swing are the least fun to practise.
When you go to your range count the number of people working on the address position versus the number of people smashing drivers!
Nevertheless I hope you are convinced by my arguments and that you will not neglect the basics.
Remember a good golf swing starts before any motion is created.
