Using a rope aid, you can give yourself a great visual to improve the plane and path of your swing. If you’re a player who takes it away outside and comes into the ball from the inside, you can set up below the rope to avoid picking the club up in the takeaway, promoting more shoulder turn on the correct plane.
Conversely, if you swing more inside on the backswing and come down over the top, start your swing on top of the rope aid, promoting a wider takeaway, bringing the club in more shallow and under the rope for better contact.
After you’ve rehearsed, seen and felt a better swing, step away from the aid and use what you’ve learned. As soon as the plane improves, the path improves, the contact gets better and you improve your ball-striking.
