Over the past 25 years I have heard hundreds of golfers not want to get their lower body moving properly because they have been inundated with people telling them not to slide.
While I agree a slide is bad, most people don’t slide, but they ruin their turn trying not to slide. I mostly see people make two mistakes here.
First I see them try and turn without letting their lower body go forward…and that usually results in an over the top slice.
Second, in trying not to slide, their lower body doesn’t turn at all and it’s an all upper body swing. This results in too many problems to list.
As long as you are turning your lower body/hips, you cannot do something that would be considered a slide.
Any time you try and restrict the movement of a body part, you end up creating tension and the swing won’t work in sync with excess tension. If you feel your zipper going a little bit toward the target, you are probably turning properly and not sliding.
This sends me on a tangent of a modern golf theory from a famous guru. Restricting the hip turn going back to increase power. BAD, BAD, BAD, IMO. Not only does that create tension, it often shuts down the hip turn and shoulder turn completely causing an all arms and hands swing.
It is my advice to never restrict the hip turn at any time in the swing.
Lastly, you don’t want your hip turn popping out of sync with you upper body. I know Bubba Watson does this, but he is an exception and if you try this, you are going to play bad golf and probably hurt yourself.
To summarize, just try and swing with fluidity, let everything turn together and keep it simple.
