Golf Swing Elements, Terminology and Definitions
Lag: When you hear us speaking of lag we are merely speaking of the relationship between the clubhead and the hands – clubHEAD Lag. In all great strokes, unless the player is intentionally applying a specialty shot, the clubhead is trailing the hands through impact….NEVER in front of the hands! Think of it this way – there is a race between the hands and the clubhead to the ball and to be an effective, and great, ball striker – the HANDS MUST WIN THE RACE!
Plane: To add a little more information about plane, please use the idea of a pitched roof and at the bottom of the roof is a gutter. We will refer the gutter as being the plane line and the amount of pitch of the roof as the plane angle. With this in mind, golfers can then envision that the plane angle can vary many degrees but the gutter of the roof or the plane line remains the same. This is why when you view good players swings they incorporate many different angles but what they abide by is that whichever end of the club is closest to the ground is always pointing at the gutter or plane line. This is the true definition of being on plane.
