Exercise

I used to walk miles everyday but, after breaking my leg at the knee a year and three months ago, it just hurt. It would send sharp pain through my knee everytime I tried. I thought I had it licked when before Christmas I actually made it to the end of my street but then it kicked in again. How frustrating because I cannot stick to an indoor exercise routine. I have joined gyms and for the first 2 weeks I am religious about going but then ...... let's just say the kids keep me hopping. Well a week ago yesterday I decided to try again. My poor dog has gotten fat and I am out of shape so.....
I did it! I actually walked without pain for two miles....TWO MILES! I have walked almost everyday since. AND my dog did not pass out either! But I am not sure she is enjoying it as much as I am....she keeps giving me that "don't you want to go back?" look. But I just keep on walking.
