My Head moves too much during the swing

Hi.

At the end of last year I started going to golf tech. Before that I was a lifter, but my head stayed pretty still during the swing. Lots of other issues, most notably checked wing arms after impact. First thing I changed was getting my hands to move in/on plane, took about 1 month. Durning this I have developed a new habit of having my head move down and out toward the ball. Here is what I do https://youtu.be/zIlzMEBOS0A. I practice a lot in front of a mirror and can make a swing without a lot of head movement. I have the flexibility. But despite trying lots of things when I hit a shot my head does this. I play to around a 10 index. I've tried lots to correct it, but not seeming to help. Any ideas are appreciated. In the mirror I am trying to get the left shoulder lower, and extend my spine as I tilt/turn.

My ball shape is a draw, which I was overdoing last week while trying this. I worked on the skateboard drill this week and it helped a lot, as my knee had been kicking in toward the ball, but this swing shows that is better, and was was hitting stranger when I played yesterday.

PS I officially joined Saguto golf a week ago. Get materials.

Thanks

Jim
