Does anyone have an understanding of how and/or why
weight bearing exercise can increase bone density? I
understand how muscle mass in increased (damage to
muscle cell, body repairs and overcompensates - a
simplistic explanation), but that doesn't seem to
relate to bones.

I did a few searches, and the only "explanation" I
could find is that exercise promotes mineralization in
the bones. I'd like a little bit more enlightenment
than that, if anyone knows....
