Fixing your Slice
Keeping Your Back to Target
There are only two reasons why someone can slice the ball - Over the top (out-to-in) starting the downswing or open clubface at impact - That's it! There are no if's, and's, or but's about it!
There are hundreds of different swing feels and thoughts that can pertain to the fundamentals preached in a golf swing. There are literally a ton of these thoughts and images that have been used by people over the years to help them strike the ball better.
Because some of these' feels' can be of value, I will give you one of my own that I think will help you achieve (a) the correct swing path and plane, or (b) a square clubface.
Keep your back facing the target at the start of the downswing.
What this 'feel' will do is keep your club to the inside on the downswing. If you open your shoulders real quick, and NOT have your back face the target, this will throw your club to the outside, and lead to an over the top swing, and hence a bad golf shot. This is a problem slicers are notorious for having.
So when you reach the top of your swing, do this?
1) Feel that your hips bump slightly laterally towards the target and then begin to turn them out of the way.
2) The key is to keep your back facing the target for a split second longer as you make this initial move with your hips. You should feel that your back resists against your lower body. Your upper body stays still, your lower body begins firing, your golf club is automatically dropped into the slot, your golf ball goes straight and far!
This is a great thought on full shots where it can be controlled by the body, because this thought is essentially just a turning of the shoulders on the back swing, holding them there for a split second, then letting them fire through.
