An interesting "maybe it's a thing" thing is happening here. As I've written, my wife has been a night and after-ride cramps sufferer. And as I've written, her cramps went way down when she upped her weekly exercise time and especially her intensity. The past few days, though for another reason, I've talked her into doing my morning stretches with me. Turns out she's much less flexible than am I and than is desirable in the areas where she's been cramping. Hasn't had a cramp since she's been doing these stretches:
