Head dipping | Golf Monthly

good ways to go would be to try to feel the swing is more centered, so body so head doesn't move away from target, 'feel' there's rotation around a center both going back then you keep your head & center as you rotate your arms & club go past your chin through the ball. what your feeling that's an issue is the lateral move away then more pronounced upper body (so head has to go with it) move laterally towards target.

do some drills with say a 7i with your feet real close together making a turn back to left arm horizontal shaft at 90º so 'L' shape & a turn to 7 through impact ( more centered rotation) feeling your arms go past your center to a reverse 'L' right arm horizontal shaft at 90º, just swing at 50%.
make any lateral move away from the ball or back to ball & through impact & you'll know as you'll easy lose balance.

it's not really 'head dipping' that's an issue.
