This golfer's wrists collapsed like crazy at the top of the backswing. They don't anymore. He also had trouble hitting out at the golf ball at all.

The fix? A bit of a two-in-one solution: TURN MORE.

The golfer was bending the wrists so much to try to feel that the clubhead was getting near parallel somewhere. Now, he doesn't have to, and yet his arms have gained not only more depth, but more distance and can thus generate more speed as well.

I'll often say to people that almost everyone can name the 17 things they don't like about their golf swing.

The trick is prioritizing the most important one, and realizing that often the other things are compensations for that high-priority item, not separate "bad" things in need of fixing.

P.S. Yes, the golfer is exaggerating a bit more than I might like in the first "after" photo. Hips have gone forward more than I might want to see, turn is a bit longer than I might want, etc. But I'll take that over the "before" particularly as he knows he's doing it slow and exaggerating it.
