Plagued with shanks, no internet drills work, you just tolerate them until they go away, try tucking in your pelvis at address, it worked for me!
I'm 61 years old, 3 capper, 5'6", flat swing, one planner, swing path in to out, strong grip, 45 years of drawing the ball.
I've had the occasional shank over the years playing but as I've got older they've become more frequent. Obviously, I'm not as flexible and so my swing has had to evolve. The past 5 years the shanks have occurred seemingly at the start of spring and would generally last for 2 weeks then disappear. I'm not talking about every shot but they'd be there at least one time per round, enough to drive you crazy. Now it's the beginning of winter and they've shown up for the past 10 days. As always, I resorted to the internet looking for the magic fix with no success. Let me back up a moment - a couple years ago during my shank fest, a local teaching pro looked at my swing and saw my strikes high on face and near hosel, he's remark, never saw that strike pattern before, lol! Anyway, normally I'd let the shanks disappear since trying to figure them out was impossible.
3 days ago while on the internet, troubleshooting my situation as a posture problem, I stumbled upon a topic over tucking in your pelvis. Holly crap, never heard of this! I always addressed the ball, bending at the waist and never really felt the feet pressure like weight into right heel on backswing and on left heel in follow through.
I've been playing the past 3 days with my pelvis tucked in and shanks are gone. I must state this was a big change, my swing plane and angles are different now I'm sure and it's taking a few rounds to embrace. I definitely feel like my swing is technically better, I feel like I'm setting/leaning against a stool as some teachers would say and I definitely can feel my feet pressure transferring between toes, ball and heels now.
I'm enjoying the back nine of my life with a new swing and outlook! Heck, I now might even learn how to fade the ball from this position but that's another topic. Hope this topic might help someone else lost and confused with those insidious shanks!
