Pushups again- Not a fluke this time anyway-

I truly expected that the next time I tried to do pushups; I would be reporting fewer than 10- the number I did yesterday. It just seemed to me that was the normal pattern of the past. So, imagine my surprise just now when I did 15!!! Unheard of. Well, it was 15 just now, and my arms feel much better. In the past right after attempts to do this, they have really been shaking uncontrolled for a time after. This time, it is only a few minutes ago that I did them, and I have no shakes from the effort. And, my back felt a bit better this time too. We shall see if this continues.
