Yay for progress on your app! Hope you get useful feedback! And yay for getting more beta comments done in addition to that, too. Good luck with getting back to the drawerfic!

I've been trying to do back-specific yoga routines and such, but I probably should do more for my back. I definitely need to do things for lower back as well - if it isn't the upper back for me then it is the lower back, or with good luck it's both. :-P That exercise you linked to actually looks suspiciously like this yoga routine I used to find helpful, only it wasn't called Superman in yoga. :-) But thanks for linking to it, because it reminds me I ought to do that one more often! Just stretching and moving the back isn't enough, I need to get the muscles stronger, too.
