Dr Mann What would you regard as the root cause of this golfers flip hand release action and left arm chicken wing ? Is my analysis below a fair reflection of a possible root cause? My AnalysisWould it be his pivot where he has swayed his pelvis too far forward over his lead leg (ie. hip/knee bypassed outer border of left foot) by P5? He has shifted most of his weight pressure over his left hip and any activation of his pelvic lateral rotary muscles will cause a clockwise rotation (away from the target) , therefore he is kicking his right knee in and/or pushing off his right foot (using his right glute to hip extend) and causing a right hip spinning action. That is blocking his right arm from doing a pitch elbow action (to help retain lag) and he is resorting to a punch elbow move causing early release and straightening of his right wrist with a flipping hand release action. His upper body pivot has also stalled by impact causing a left arm chicken wing through impact. What would be your recommendation for him to cure this non-optimal hand release action? DG

His upper body pivot has also stalled by impact causing a left arm chicken wing through impact. What would be your recommendation for him to cure this non-optimal hand release action? DG Although his pelvic motion during his early-mid downswing is sub-optimal, I don't think that his imperfect pivot action is causing his pre-impact flipping problem. I think that his major problem is that he not using a TGM swinging action, and he is probably using a swing-hitter's technique. Here are capture images from his swing video.
image 1 is at P4. He has loaded his right-sided lateral pelvic rotator muscles well by driving his right hip joint into internal rotation while maintaining right knee flex. He has a rightwards-centralised upper torso loading pattern. He looks reasonably good at P4.
Image 2 is at P5. I agree that he has too much left-lateral pelvic shift, but his power package is well retained and his right elbow is visible below his left arm, which means that he is adducting his right arm well enough while maintaining a bent right elbow. Image 3 is at P5.5. Note that he has retained lag well enough using a pitch elbow motion of his right arm.
Image 4 is at impact - where he manifests a bent left elbow (chicken-winged left arm), bent left wrist and a straightened right wrist - all biomechanical features of a pre-impact flipper. I think that the likely cause is that he converts to a hitter's action at P5.5 (where he activates PA#1 while allowing his right wrist to straighten) and he is not using a TGM swinging action between P5.5 and impact.
I think that he needs to first learn how to perform a pivot-induced TGM swinging action using only his lead arm - as demonstrated by Sasho MacKenzie in the following you-tube video.

Many thanks Dr Mann - I have referred the golfer to this site to read your analysis.
