She may only have meant the final pose at the end of class...and it might have just FELT like 10 minutes Anyway, I will give it a shot at some point soon. I see my PT today so hopefully we can figure some of this out. Had lumbar stiffness during spinning class last night - my tail bone was aching. It has done that before, but not often.

Melalvai, I do catch myself slouching more than I realize, so will work on this as well. Everything is connected, for sure.

I have been told that my spine doesn't have as much curve in it as "normal" by one of the other personal trainers when I first joined my sports club. Indeed he was surprised that I didn't have back pain...
