You need to slow down and work on the smaller motions. It's going to feel wildly different correcting this.
I'll rewatch the videos you linked, but if you had anything extra to say on that subject that would be awesome. It's always been a weird one for me.
If you compare your throw to doing that battering ram drill (and post it to check if you're doing it right), the way you're throwing now would lead the ram to pulling you around in front of and around your brace off balance. The front shoulder should be low like shoveling snow so what when you land you can get power swinging more directly balanced over your front leg, which Power of Posture is all about.
Part of the "open/closed hips" and "shift from in front" story is about how you load and move off the rear side. Compare a dude actually swinging a ram to Paul's backswing:
If the guy on the left was swinging a ram or weight with one hand and swinging back farther braced correctly on his rear leg, it would pull his hips "closed" to the target with his upper body as it turns away, making his butt lead like Paul. Then he would still be shifting off that rear leg right back at the door and swing the ram or weight balanced on the front leg.
You can also swing a weight back and forth shuffling laterally sideways, btw, which I wish I'd done more earlier. But you need to start learning what it teaches you about posture in any case.
Also, I recommend you re-use the same form thread each time. Context and history matter!
Assuming that these are all you, I learned that you are a baseball player who had trouble learning to switch hit, and noticed that you don't seem to follow up after initial posts in different threads. Your throw seems to have gone from controlled to kind of violent and forced. I have the strong suspicion that you are trying to brute force your way to distance without slowing down to learn how to move. Maybe you'll figure it out on your own, but your queries and history suggest that you would benefit from a different strategy. Where would you place your bet?
I'm happy to help fill in the blanks having been through many of these drills and having them critiqued, and saying things in different ways can help different people. But I think actually doing the battering ram and posting it might teach you more than you think - it will if you let it.
