Why does a Single Plane Swing work? Quite simply, it is the easiest way to accommodate the tangential momentum of the clubhead.
What does that mean? Most refer to it as “centrifugal force” or what is sensed as an outward pull of the clubhead when swinging at high speed. This force literally pulls both arms to extension on plane with the clubshaft at a point beyond impact in all golf swings.You can see this same reaction in baseball swings and the hammer throw, too. It is a natural human response to swinging a weight attached to the end of a stick; the arms will align on plane with the stick during the swing.

Engineers have also proven the Single Plane Swing is the most efficient to use by building equipment testing machines by aligning the clubshaft on plane with the swing arm. In the Single Plane Swing, the golfer aligns their arms with the clubshaft at setup so the ball is positioned where it will easily be struck as this same arm/clubshaft alignment is attained during the swing. It’s simple . . . start where you are going and swing through during impact. This way, motion is minimized, consistency is optimized and it is virtually stress free to the body.
The conventional setup positions the clubhead, and therefore the golf ball, closer to the golfer than the distance achieved during swing extension by recommending that the arms hang such that the hands hold the club below the shoulders. This instantly creates an angle between the clubshaft and trail forearm that will not be there during the swing. The trail forearm will align with the clubshaft through impact and the golfer will have to accommodate this alignment by repositioning the body during the swing.
If a golfer addresses the golf ball closer than the distance achieved at full on plane extension, they will have to move their body out of the way to both hit the ball and make room for arm/clubshaft alignment. This is usually seen as an “up and back” motion with the torso. While world class athletes can accomplish this complicated movement through constant practice, the average golfer generally “comes over the top” of most of their golf shots producing pulls or slices...or they miss time the motion completely and hit fat or topped shots. All the “in-swing” body motion required may also causes more stress on backs, hips and shoulders, making playing golf regularly for some an impossibility.
So you have a choice to make – create an angle between your arms and clubshaft at address and spend your golf round jumping out the way of their inevitable alignment during the swing while you try to consistently hit the ball to your target . . .
