I saw this on Morning Drive yesterday and knew right then that I wanted to post this today. Their Coach of the Week, Jason Sedan, has the computer motion studies of Jamie Sadlowski's swing and it shows that restricting your lower body is NOT the way to create clubhead speed. Instead, you have to let your hips turn freely.
Look, I'm not even going to try and explain what he's talking about here. But I do want you to go back to this video I posted of Arnold Palmer's swing during his heyday. Pay particular attention to his hip turn. Look familiar?
