Advice that I is a word to self

Sadly all I did was walk slowly for a while.  I did no dancing or anything strenuous at all today.  I guess I need to do more stretches.  Stretching my muscles are good for my back.  I need to have my spine straightened out.  Plus I have carried most of my weight in the middle which doesn't help.  Maybe I do have to start slow.  If I don't, I will eventually give up.
