I miss hip flexion, somedays I can only get 100 degrees without impingement. On other days up to 120. And I miss a lot of internal rotation, especially on the left leg. That and my restricted ankles makes it impossible to squat ass to grass without a buttwink!
For example, if I do a pigeon pose for 3 minutes I get really uncomfortable in the back leg which is in hip extension, and the next that I feel like sore in the front of the hip and have less hip flexion.

I hadn’t seen the last video from above, but what the pregnant lady in red said was exectly the same problem I that I have. When I squat I feel really unstable and like my pubic bones are moving.
My flexibility wasn’t that bad a while ago, but I had not thought that I could ever be too mobile? LOL
