Tonight I had company; I was joined in my workout by Miss P#4. Once again, I was not surprised to be unable to keep up with the entire workout, but again, there was a slight improvement in more than one area (most notably flexibility). This is very encouraging, because it makes me realize that even a little effort can pay off, and sooner than one might expect. One big difference: after the workout on the first day, my legs felt like rubber for hours afterwards; today, after only three workouts, they felt fine almost immediately afterwards. I just have to try to find time to do this earlier in the day, when I have more energy.
