re: Easiest way to fix out-in swing path

“Reverse the loop”: exagerate taking the club away to the outside of your target line and then feel like your hands are dropping towards the ground at the start of your downswing. Watch videos of Lee Trevino swinging driver down the line to see what it should look like. (Like the clubhead is making a big counterclockwise loop.). Again, really exaggerate this in practice to groove the feeling and then dial it back a bit once you’ve got it.
