It would be interesting to know where exactly it is during the back swing that the bobbing occurs. Start-up, back swing, top, end? Personally, I hold the record for swaying and bobbing, and I don't like it when someone else is encroaching on my record, so, it's important to get you fixed as soon as possible. I've asked my wife to watch me swing and to tell me when I start to bob, and so far I have address and finish pretty well under control.
7-16 "Actually, the primary function of knee action-as with waist bend-is to maintain a motionless head during the stroke".
It looks to me that MOST Bobs(backswing bobs) occur fairly late, as the player nears the TOP.
Now... what I'm interested in is WHERE(in the body) it is originating from, and WHY is it happening?
>Is it from a physical restriction, so the player sub-consciously raises the torso some in order to complete his Turn more easily?
>Is it from a reaction related to the golfer's attempt to elevate his arms?
>Is it a VISUAL thing?
WHERE> Is the BOB originating from the PELVIS area, the CERVICAL spine(neck), THORACIC(mid-back),or LUMBAR(low back), or other?
Lagster,
To help with your research please consider the following.
On good days, I don't bob or sway. On bad days, I do both. Arms, hands, clubshaft, upper torso staying connected during takeaway and backswing = no bob. Arms takeaway = bob, but not always. I've had some very good days using right forearm takeaway and I prefer it. However, my body is much more stable with a connected takeaway.
Having been trying to learn the golfing machine i've realised bobbing is something i've always struggled with.
My head rises towards the top of the backswing and perhaps more worringly doesn't move down again on the downswing. I've tried to stop many times and failed. Having seen it listed on the TMG basic essentials i thought it was worth another shot at trying to cure.
Unfortunately it is easier said than done. I can concentrate on keeping the head level and can do so, but i can still feel the pressure wanting my head to rise. Consequently everytime i don't think about it i go back to bobbing.
For me i think the bobbing is caused by tension in the left shoulder created by the lifting of the arms in the backswing. I've tried experimenting with a shoulder turn takeaway, using the body to propel the arms to the top. I think this has help slightly but not as much as i'd like.
