Wow! I just found the Every Body Walk website through the most amazing video I have seen in a very long time. This is George Halvorson the chairman and CEO of the Kaiser Institute in Washington DC. He is speaking of the countless benefits of walking just 30 minutes a day.
I would suggest that you watch it more than once because there is just so much information packed into a short period of time.
I have always felt that you really can't do better than getting out and walking for 30 minutes a day but if you ever doubted that it is a powerful practice you won't after you see this video.
I am heading out the door with Dave in a few minutes to walk30 (or so) with the Walk On Strong group in Waterloo and I have to say that I feel even more motivated.
Walk on Strong!
