What do they mean by "Weight Transfer"?

There are many confusing and, seemingly, contradictory advices given by Coaches & Teachers
that it is no wonder our golfing brains become like bowls of spaghetti!

We know that we must keep our head still and that it remains "behind" the ball through impact.

We know that the spine angle must remain constant throughout the backswing and forward swing.

We know that the golf swing begins from the ground up and that we need a stable base/platform to create the inertia and centrifugal forces for club head speed.

We know that the Body must turn twice ON ONE AXIS ... so HOW does "Weight Transfer" fit into all of this?

Teachers of the Modern Game recommend that the Knees that sit above the Feet at address should retain their position throughout the backswing, resisting the urge to move closer to each other, as the Upper Body rotates going back.  Furthermore they recommend, just as the Discus-Thrower, a feeling of downward pressure into/onto the Right Heel in the backswing.

In the forward swing they recommend a feeling of "pushing upward" with Hips rotating [again like the Discus-Thrower] that permits the Arms to "be swung freely" through the impact zone.

Because the Upper Body, Hips and Knees are "stacked" throughout the backswing and forward swing[Upper Body turning, Hips rotating and Legs resisting] there is a strong IMPRESSION  of "Weight Transfer".

Weight Transfer is an IMPRESSION that you get when all of the above takes place.

Please do NOT attempt to "transfer your weight".  Too much leg-action whilst at the same time attempting to keep your Head still leads to sore backs, blocked or thinned shots, hooks, frustration and despair!
