I couldn't resist posting this, simply because it shows why weekend players get so confused. Plus, if you've struggled with Gary Player's step through drill, why not step away from the target with this drill from Butch Harmon?
Essentially, Butch has you set up with a narrow stance -- roughly a foot wide -- then step back with your trailing foot as you start your backswing. The idea is that you'll naturally push toward the target as you start your downswing, hence shifting your weight to your lead foot and improving your weight shift. No more reverse pivot.
As for the Player VS Harmon drill debate, I'm not telling you that one is better than the other. It all depends on whether you need the "rocking" motion that this drill sets up or not, to get that shift to your lead foot. My advice? If weight shifts and reverse pivots are a problem for you, try them both and use the one that gives you the desired result.
