@neckcracker12 No, never

I have cracked my sacrum for years now. But I think I have manage to crack it in the joint with the lowest lumbar on method 1, that is the most I've seen describe here, and with method 2 I almost sure I'm cracking the joints of the sacrum with the Iliac.

Method 1: Similarly to many of the read above: let my legs and lower back hang relaxed by supporting my body with my arms like in gymnastics' parallel bars. I do it sitting or standing. I use Low walls, better if low wall corners, 2 paralel chairs work, chair with arms, and alike.

Method 2 Some months ago, I discivered a crack down in the deep middle of my pelvis. Certainly, the sacrum. It was serendipitous, since now and then I strongly compress my buttocks for relaxation, as I got to like this from the sitting horse kung fu position. Now I do it for the crack compressing the gluteum trying to push them inside my crack and upwards for round full eye-wetting multiple crack . Indeed when fully achieved is a physical pleasure only second to o****m. However seems that is not a lond lasting crack, after just less than year I can only crack it "saving it" several days and even then the full one I get only sporadicly. Maybe is something about age. I read the sacrum fully stiffens after the mid 30s
