One Plane Swing

One Plane Golf Swing. 

I believe this one (single) plane golf swing would be the most important concept for the great ball striking.  One plane golf swing simply eliminates so many potential problems and issues. 

First, think of two flat wood boards which stand next to you, on left and right side with the same slanting angle as when you stretch out the left hand with golf club. 

Your arm and golf club together make almost one straight line pointing to the ball sitting on the ground.  The line may not be 100% straight, but almost straight.  Because of this, the handle will be farther away from the body or belly, unlike the conventional position when line of arm and line of golf club with holding hand will be clearly kinked. 

I am trying to get you to the idea of ONE Plane golf swing - ONE PLANE.
