I would say you take the club back outside and in a manner that sets you up for an over the top downswing. For that reason and maybe many others- your subconscious correction (improper) has been to flex the knees during the startdown/downstroke to prevent rotation and offset the backswing problem. In addition, as you finish the backswing and segway into the downswing- you get well to your left side with the upper body- again to help prevent the pulled shot, etc. .
I would see the body motion as an effect and go about correcting it as such. I wouldn't think about holding your center still etc. The body motion is an effect- you need to understand the cause.
Mr. Kelley had an article in Golf Magazine in the early 80's. Of course, the magazine changes things by the time it makes it to print but before that - his description of Bobby Clampett's Downstroke may shed some light on your stroke.
"Bobby is in a bit of a bind here because his left shoulder instead of his right shoulder moved downward. But he can and does recover in time for release. A common present-day misconception is surfacing here. That is a partial, preliminary weight shift through knee motion instead of hip motion which disrupts the on plane start down shoulder turn essential to establishing the precise direction of both the hands and the clubhead.........."
Finally, my best advice would be this "I wouldn't look for advice from Bucket or myself" - that's just wrong! And for some reason even after that advice - you're thinking that taking such advice sounds like a good idea- SEE A DOCTOR- and I'm not talking GSED!
P.S. Bucket- You've been reading too many stack and tilt articles!!
