Several months ago I had a post regarding how much should the left arm rotate on the backswing. A great discussion arose of who nows more and yet I think the question was forgotten. I have always had a very upright backswing and am trying to flatten it or get on plane. My thoughts are to rotate the left arm more on the backswing , this seems like a reasonable fix but how do you know without video tapping , if it is the right amount or to much. TIM
RE-POST OF LEFT ARM ROTATION

Tim,
Focus on the alignments of the Left Hand -- specifically the Flat Left Wrist -- not on the Left Arm. Then, as a Swinger, use Standard Wrist Action (10-18-A) to immediately Turn the Left Hand 'Palm Down to the Plane' during Start-Up and maintain that alignment to The Top.
Alternatively, particularly for Hitters, let your Pivot and Arm Swing gradually bring your Left Hand to that identical 'Palm Down to the Plane' alignment at The Top. This is using Hinge Action (7-10) -- either Horizontal (Swingers 10-18-C-1) or Angled (Hitters 10-18-C-2) -- as a substitute for Wrist Action.
An important point: In Standard Wrist Action, the Hand is independently Turned (Swiveled via the Left Forearm). Using the Hinge Action Variation, the Hand Turns, but it is not Turned (Swiveled).
)]) and a roll is counter clockwise.Speaking of wrist turn, here we see Sergio's downswing. It seems he rotates the left wrist, "flattening" the club on the way down. Would this be a reverse shift downswing (10-7E)? Would it also be downstroke loading (10-19B) ? Also, the clubshaft is clearly pointing to a point outside the ball in the second picture. This seems to be a violation of "good players make on-plane strokes".

For a 'true' swingers motion, imagine the hands basically 'clap' onto the plane, and rotate around the tip of your middle finger. A lot of rotation at this extreme, vs. hitting where there should be very little.
It is a question of physics (swinging) vs. geometry (hitting).
Of course both require an understanding of anatomy. If you first learn what the club 'should' do (geometery) then what it actually does (physics) you can learn how to best use your body to support that understanding (anatomy).
IMO that ideal is closer to Alex Morrison (which BTW is somewhat similar in many ways to Ben's motion).
The big question is that of transfer power, the heart of the question about forearm rotation.

The swinger's downswing is easy.
As you uncock, you are coming 'into the ball' with a "Karate Chop" left hand.
You then transfer the speed in the clubhead from un-cocking to roll and BACKHAND impact.

Purely out of curiosity, what if the alignments at Impact Fix of the hands to the swing center is not changed on the backswing but simply rotated by the pivot, and raised by vertical hinge action, what would this cause the club to do? Is it possible to correlate the vertical hinge and the backswing pivot to create the proper backswing plane?
