How to Stop Sliding (or Swaying) on the Downswing
There is a little bit of lateral movement at the start of your downswing. But if you slide your hips too much, it will cause all kinds of bad shots.
The best way to fix this is to change your grip. Lots of times golfers who slide their hips too much tend to have a weaker grip.
Simple Drill to Fix Sliding
Here is a simple drill to fix sliding of your hips on the downswing.
1. Set up to the ball as usual
2. Turn your left toe inward
2. Take a few practice swings
This should feel awkward at first. When you take a practice swing, swing slowly.
After taking a few practice swings, start hitting some balls. You should tee the ball up and hit it with a half swing.
This drill should prevent you from sliding toward the target. If you slice the ball, try to face the back of your left hand toward the ground on the downswing.
One of the reasons why you slide your hips is a reverse pivot. If you slide on the backswing, you have to slide back on the downswing.
If that's the case, try to fix your reverse pivot.
