Thanks Esther for this amazing research! This would be so fun to research.
I had a quick question about my spine. So my spine is a little messed up because once you reach L5 it's deep in my back and there's basically a hole there. This makes the anteverted pelvis much harder for me and I have a few spin segments that stick out along my back. I've tried all the spine lengthening techniques to bring it out but it won't. I also had an MRI done on my low back for other reasons and here is the conclusion.
I also have forward head posture and a few other things (I did get Nuss procedure done so I do have bars in my chest). The forward head will go away once I figure out how to stretch my mid spine because that's where I feel tension when I try and bring it back. I feel because it's L5 it affects everything more since it's the bottom of my spine.
I guess I'm wondering if there's any way around the defenct in my L5? I realize everything is connected so I'm not worried about the lordosis or anything like that. I can see how this method works as I can do fragments of it and how it all works together.
