I did myself in. See all those planks? They are really heavy. I lifted them up and down for hours all last week moving them from place to place so it was no surprise when I woke up at 5 am yesterday in the worse pain from my neck to my lower back. Between The Mister's knees and my neck and shoulders we took the day off and had some serious couch time. We did get two whole rows down the day before. I think we've cracked the code. Now we just have to heal.
