Forward bend at address
Left tilt toward the ball at the top
Right tilt toward the ball at impact
These three vastly different positions create what appears from behind the golf (down the line) to be what people would call “maintaining the spine angle,” but it doesn’t.
…and the tilt of the spine away from the target will increase, especially with driver, to start the downswing.
I know this isn’t earth shattering info, I just want people who don’t know this…to know it…as roughly half my lessons in November who brought up the subject didn’t know this.
People interpret this wrong and mess up their swings.
