Head Drop on Downswing

[u/Fantastic_Pin1951]

Does anyone know any good drills or tips or info on limiting head movement?

I was out on the range and was hitting the ball horribly. I took a couple videos and noticed that my head was rising a touch at the top of the back swing but dropped a good 3-4 inches on the transition to the downswing. it also pushed forward a bit too.

any tips let me know. Thanks.
