The dreaded reverse pivot

Any help would be appreciated. I am doing this weird reverse pivot thing and can't stop. Ever since I started trying S&T;, I've ingrained this bad habit. I've followed things here and am impressed with the whole 5SK direction. Anyway, I apologize, I don't have a swing video just yet, but basically, my butt swings out toward the target on my backswing, and then often reverses course on the downswing. As you can imagine, I have lots of issues then.

Is there any help that can be offered here without seeing my swing? Any particular drills I should focus on? I've done several drills (though admittedly without much of a plan) from the 5SK thread, particularly the ones focusing on weight forward at impact. I've tried to feel what that position is like, but am still struggling with it. My other big problem is that I massively struggle with moving my upper center forward when trying to get my weight forward. I *know* that's not right, but it's what my body does instinctively. When I try to get forward, my head goes forward. I always feel like if my head stays stationary, my swing bottoms out well behind the ball. So that's a whole laundry list of issues I guess, but any help is greatly appreciated.

You've mentioned a number of issues, but I'll try to boil it down to just a couple things.

OK: the definition of a reverse pivot is when one's weight goes forward in the backswing and then shifts to the back foot on the downswing. Obviously, as you know, that's a huge no-no in golf.

If your weight is going forward and your head is tipping down and forward, then you need to focus on turning in flexion more in your backswing and getting your shoulder turn to go back far enough, like towards your back foot. You may also need to feel like you are shifting pressure into your back foot, but this is difficult to say with certainty without swing video.

Here's a video of me working on my backswing a few months ago, and it could help with your backswing issues:

I left too much weight forward and had too much extension. As a result, my head tipped forward. Of course, I didn't have a reserve pivot because my weight/pressure still went forward on the downswing, but this video might help you better understand your own backswing deficiencies.

Note the location of the lead shoulder's low point is different in both swings. Note the location of the lead knee is different in both swings. In the correct swing, my left shoulder reaches its low point in the center of my stance.

On the downswing, you likely need to feel an enormous amount of pressure being applied to your front foot so your hips can make their lateral shift towards the target.

As for what your upper body should or shouldn't be doing on that downswing, well, that too difficult to pinpoint without video. If your head is moving forward towards the target and not staying relatively stable, then you might need to feel your spine extending while your pressure/hips are going forward. You could even possibly need to feel like your head is tipping back -- you wouldn't want to actually tip your head back, but that feeling could help you keep it from going forward.

This video could help with your downswing issues:

There's more that goes into this stuff than what I've talked about, but without swing video to work with, I'm basically just throwing spitballs at the wall with a blindfold on and hoping something sticks. But I hope that helps you a bit as I'm playing the probability game here.
