Below you can see how my PFTs trended up over the course of my IV treatment from Aug 29 to Sept 18. (I started keeping track of some of my medical stats in a google spreadsheet and it allows me to easily make nifty graphs like this.)
I have been keeping up my end of the bargain! I have exercised 11 of of the 17 days since my appointment - swimming, walking, elliptical, even yoga! And I have done so in a mindful way with respect to my back issues, which will always be with me creeping up from time to time.
So yes, last week I went to yoga class for the first time in about a year and a half. It was a huge milestone for me. And I went to another one tonight at a new studio. Both of the classes were restorative classes (also called yin yoga), which means mostly passive positions to let your muscles and soft tissue release tension. Very relaxing and, well, restorative. It's a far cry from my cardio-workout flow yoga classes that are my real love, but you have to start somewhere. Baby steps. I used to hate baby steps but I am seeing their value in my wise old age.
