I started tuesday, September 4, 2007 walking just around the hospial in my little town. 6 times around it equals close to a mile. The only time I can walk is on my lunch break, and so I only walked around it twice tuesday and 4 times wednesday. I was just wondering how much I need to walk if I am not doing any other exercises? I also have a treadmill at home that I could walk on. I would just like an average to go by since I just started.
