@genlty I cannot access that link. I thought cortical porosity was a key to flexibilty, but not strength. I have not seen any studies on this idea or the one you cite, and wish I could read it.

I have noticed that treatment, at least with Evenity and Reclast, has made me stiffer, less able to lift or reach w/out pain. I don't recall this effect with Tymlos. It does make me wonder about bone density vs flexibility.
