Saturdays Run

The question I am asking myself today is:
Every time I sit in a chair, or ride in the car, I can barely move when getting up. For the last week,it has taken my body a few minutes to Get with the Program!   
So,  how could I go on a three mile run this morning and feel great? 


This just does not make since to me! Then, I went shopping with hubby and I could barely get out of the car each time we stopped.  It seems like once I get moving my joints feel better. It is the sitting that is not working for me!!!
