I continue with a few minutes of the pedal exerciser most evenings. Did my qi gong twice this week. Today, I pushed the cart and did an intensive 25 minutes at the grocery store. I try to do it as fast as possible without getting uncomfortable. Having something to push helps me stay steady and trudge on. I also walked about another ten minutes this morning. What little muscle i had went south over the past three months. It is a long and slow climb up, but I'm definitely improving.
