This is yet another of these cliche terms that gets thrown around by everyone and most have no idea what it is or how to use it.
Float loading is a natural process that happens in CERTAIN golf swings. There is very little wrist cock on the back swing and the change of direction causes the wrists to set naturally on the way down. It can create power and a great strike at the ball…as long as it is a natural process and happens in sync with the turn of the body. Lucas Glover, as an example.
The problem is people see this action as a great way to create lag and they force this move into their swing.
As a matter of fact, there are actually people who teach their students to take the club away so the shaft and arms are at a 180* angle and then massively pull down with the hands creating as small of an angle as possible.
In other words, the arms and the shaft on the takeaway are one straight line. When the back swing transitions to the down swing, the wrists massively cock sending the straight line into an small acute angle…the smaller the better for maximum power.
I call the people who teach this…IDIOTS.
If your natural golf swing has natural float loading…great. If someone describes the float loading process to you and tries to get you to do it to create more power, more lag, or cure a casting motion…take off your golf glove and slap them in the face with it. They are trying to ruin your golf game.
Look at this nasty, forced action.
