An age old problem of flipping the club through impact has a couple possible causes.
1. Most common cause is an off plane swing path. Typically, a swing path (plane) that is too steep (out to in) results in the shaft swinging in and up at impact = open clubface, loss of power and toe strikes. Less common is swing path that is too shallow (in to out) = right hand overactive in an effort to square the clubface at impact. This can result in loss of power, blocked shots, quick hooks, topped and thin shots.
2. A Strong right hand grip (trail hand) will allow the right hand to be positioned in “Hammer Mode” where left wrist is cupped (Dorsiflexion) and right wrist bowed (Palmarflexion) at impact that can result in quick hooks, topped and thin shots or high right shots.
Correct impact position = Left arm (lead) straight in line with shaft, left wrist flat.. right wrist bent back… both arms straight and extended in front of chest past impact.
Using the impact bag as demonstrated in the attached video is a great way to feel the correct impact position and “Stop the Flip”
