Could you elaborate on what this is promoting? Is this like a stop for the left arm so that it momentum from backswing doesn't cause the club to fall behind (inside, flat, what have you) as he starts his rotation? Or is it forcing a low left finish (as we see when he bangs his hand on the stick early in the video)? I'm always interested in what Hideki's doing because drill-wise he's really at the bleeding edge (I still do trail hand only with lead hand tucked behind trail tricep, but I know what that drill should do) but it's hard to tell if this is applicable without some idea of what he's looking for here.
It’s not for swinging over the top necessarily. Hideki has always had an issue with that giant pause where he fired his hips and got stuck. Arms way behind him. He’s worked more recently on getting the arms to work down his chest more and not rip his body open early. Getting things more in sync with each other. I watched him hit balls for an hour 10 years ago at the Silverado tournament in Cali and it was so obvious he was stuck behind. This is necessary. This drill helps in a couple ways, for one you can’t trail your arms and have the stick point the right way. Also he might be trying to feel like he’s working under it through impact. Not really sure his personal feels. But he’s never had an issue with over the top. He’s always been a really stuck golfer and it was worse before with how he used to massively fire his hips.
yes,I have a ph.D in golf physics and masters in kinematics and 2 bachelors in biomechanical engineering and mechanical engineering so I can absolutely explain what the stick is doing for this man. The stick being under his arm pit promotes collection of sweat which leads to odor, which attracts bacteria and fungus, which can lead to a condition called systemic Hirschsprung infundibulum diverticulosis meningitis. Which in layman's term is called major constipation. The stick has nothing to do with his swing. he has it there to promote bowel movement when he feels that he can't no longer turn freely.
