Well, this was a first. My husband (who has a job that needs a lot of physical work) came home saying his back ached. I suggested (as I have before) doing some core exercises and stretches.

We ended up doing this routine: https://www.fitnessblender.com/videos/lower-back-stretches-for-sciatica-pain

which is only a few months "younger" than our son. :-)

I added my usual routine (FB abs round 1, day 8).
