Rory McIlroy has a great-looking swing motion. Very little lateral motion and a nice, pure rotation around the spine during the back swing.
He has a “Modern Golf Swing” which involves swing with both feet planted firmly on the ground to restrict the hip turn from Address to the Top.
I personally don’t like the Modern Golf Swing because of the stress it puts on the knees and lower back.
Rory Down the Line
The old-time Classic Golf Swing used the hips and legs so it was performed with a full hip turn, so you would see a lifting or “floating” leading heel on the back swing, but the modern swing restricts the hips and is overly focused on upper body action.
You can swing like Rory as well, if you’re fairly fit and flexible.
But you’re courting lower back problems as you get older, due to the stress it puts on the lower back in particular, but many other parts of the body.
