and back to square 1

My week; 3.5 miles :(
What happened? Woke up Monday morning feeling good. Went to work and my back started to ache. No biggie, right? Well for someone who has sufferd thru a back surgery it is a big deal! I think I just did too much without paying attention to my core. And doing more core was a New Years resolution. Had to do when you are hurting. So I'm out the door today to walk/jog in the Garden and see what happens. Then down to the basement for core exercise.
