In the image above, three different planes along which the golf club can travel are depicted:

1. Shaft Plane (Lowest Line): This is the angle created by the golf club's shaft.
2. Elbow Plane (Middle Line): This plane is aligned with the golfer's elbows.
3. Shoulder Plane (Top Line): This is the highest plane, aligned with the golfer's shoulders.

Choosing the right plane for you:

It's crucial to understand that there is no universally "good" or "bad" plane. The optimal plane for you depends on your unique physique and swing style. The right-hand position on the club directly impacts the swing plane, and aligning these elements is essential for unlocking your true golfing potential. This alignment is considered the most crucial variable in golf.

How to determine your ideal plane and grip:

Here's a simple test to help you identify the plane and grip that work best for you:

• Get into position:
  • Assume your regular golf posture.
  • Place your hands together in front of you.
• Perform the swing:
  • Keep your chest stationary.
  • Swing your hands up to chest height.
  • Allow your right arm to fold naturally as you do this.
• Observe your right arm:
  • Pay attention to how your right arm folds.
  • Note the direction in which the palm of your right-hand points.

Interpreting the results:

The Shaft Plane

When your right elbow tucks in, and the hand faces the sky, the preferred grip is where your right hand is some amount “under” the handle (rotated more to the right for a right-handed golfer). Some examples are Dustin Johnson, Justin Thomas, and Adam Scott.

“Under” golfers will swing their best when they fold their right arm into their body on the backswing. Imagine “tucking” your elbow into your side.

The elbow Plane

If your arm folds the elbow to the shirt seam, and the hand points horizontally, you can use a side on to neutral grip, like Billy Horschel, Justin Rose, or Tiger Woods.

The shoulder plane

If your right hand points more toward the ground in front of you (right), and your elbow folds up and back — grip the club with your right hand more “on top” of the handle, a hold used by Rory McIlroy and famously ben hogan who used this hold to eliminate his hook.
