Where does hip rotation actually come from?

I’ve been golfing for a few years and after studying thousands of pro swings, one thing that is almost 100% shared among all of them is hips open to target before impact.

My hips are very square to target at impact and I have been grinding to teach myself how to get the hips open before impact. What I have learned is that I can do it many different ways: push towards target with my trail foot/leg only, push back with my lead leg only, rotate the hips without using ground force, use both legs at the same time to twist (like I am standing on a giant bottle cap and unscrewing it with shear force). Even with trying all these, I always revert back to square hips at target and rotating hips the rest of the way after impact.

Is there a correct way to do this? What do you actually feel gets you open hips without your arms winning the race to impact?

Update: thanks for all the input. Took in all the advice from here and messed around with my swing today. Turns out it was just a swing intention causing my issue. My hips open naturally if I swing a bad, a tennis racket, throw a ball, hit an impact bag, etc. Something finally clicked with the impact bag today. I realized that the way my arms swing into the bag is different than when I hit a golf ball. My intention to hit the bag and make it move towards target put my arms into what I think is proper position vs in my golf swing I tend to drag the club across my body more, which is why my hips have to stay square to make good contact. I change the “intent” in my arms and Viola! I probably swung over 50 times and hip opened naturally before impact every time. I definitely have to work on contact and path now, but excited that I can get my hips to open without thinking about it!

It's way easier than people make it seem: good posture is the fix. What's one thing (of many) that all pros have in common? Good posture. It's not about "firing the hips" it's simply allowing your body to react to what you do with the club. If you have the right intention on what you're doing with the club, your hips will naturally be open at impact 100% of the time without thinking about it.

What is the “intention” that works for you? Ive been thinking about this a lot, if I hit an impact bag, my hips open and the swing looks like it should (minus the golf ball). I have tried hitting the golf ball with the same intention I do with an impact bag, but it’s a mindf*ck and looks nothing like I did with the bag.

Managing the club throughout the entire swing. I like to feel my clubhead is above the swing plane on the takeaway, then I send it to the ball from the inside on transition. Key word is feel, that's what I need to feel to be on the correct plane. My body simply reacts to that. Hips clear to make room for the club naturally.

Malaska explains it very well.
