Weight Distribution in the Golf Swing
In general, where your club goes, your weight should follow. On the backswing, your weight should shift to your back foot, helping to create a proper, balanced turn.
There are several different theories about weight transfer, but most instructors will agree that properly transferring your weight is a fundamental component of an effictive backswing.
It is important for all golfers to realise that the weight distribution at the address position should be different depending on whether you are using and iron or a wood.
With your woods you should adopt a nice wide stance with the ball set just inside your font heel.
