Head dropping during backswing

[BerntR]

Maybe you should check your shoulder turn and the arms pickup & turn. The shoulder turn in the back swing can be very flat. Check that you're turning and not tilting.

You don't need to lift anything with your shoulders. The arms have a steeper job and do most of the lifting.

You might wanna check your weight shift too. Right foot pressure from the top and standing on the left foot in the finish.
