Tee is too high. I have DD use a little 12 inch cone and tell her to get it in the air.(line drive) You should try it. It might help you with your staying in your posture.
Today's swing. I think I'm holding the hinge angle during initiation better. Needs some more work. My cue was to swing down, lower the back elbow. So, I'm lowering the back elbow first and lowering it creates a swinging down action. It helped I think.
Posture still needs work, still coming out of it too early.
As you can see I'm starting with a open stance to better feel the back leg/hip load. I swear I was striding farther forward. In some of my swings I did.
