Setting a physical gate along your target line forces the club to swing on path rather than over the top.
Set-up: Two objects (headcovers, cones or alignment sticks) set a foot or two in front of the ball, or alongside it, as a channel the club must swing along; swing through without touching either.
This setup uses two props set beside or in front of the ball to form a visual gate for the clubhead.
Position your physical props Place two headcovers a couple of feet in front of the ball or set alignment sticks on either side of it to frame the target path.
Adjust the channel width Set the objects wider than your clubface initially and bring them closer together as you gain control.
Swing through the channel Focus on passing the clubhead cleanly through the gate without touching either prop to encourage an inside-to-out path.
Common mistakes
What goes wrong
Swinging over the top Focus on passing through the channel to prevent the clubhead from coming in from the outside.
Looking at daunting distant targets Keep your focus on the visual gate close in front of you rather than staring downrange.
