Over the years I’ve heard way too many am’s telling their playing partners or family members to keep their head down or on every miss hit they’ll say “You picked your head up!”.
In some cases the advice giver is correct on the end result but nearly always caused by another major issue. Often the amateur’s student has heard, keep your head down, so much that they bury their chin down so low they can not turn properly or they become so locked in on the golf ball they loose all proper swing mechanic’s.
