‘Stand taller to swing on a neutral plane’
Posture is a really important part of the swing and I’ve improved and stabilised mine a lot recently. I used to sit back on my heels with really bent knees so the club would lift off-plane on the way back, get a bit laid off at the top and then drop it under the neutral plane in the downswing and flip at it with my hands through impact. Standing taller has made my swing less reliant on timing with my hands and more consistent. It could help you too.
