No need to run
It is reported in a recent issue of Chest that in a study of 133, middle-age, over weight and sedentary folks at risk for heart disease, 12 miles of walking a week at a moderate pace did just as much good as 12 miles of jogging or brisk walking. I'm taking a wild guess here, but don't you think the 12 miles is the key? That's 2 miles a day, 6 days a week, with time out to go to church on Sunday. If you're a slug or a couch potato even 15 minutes a day would be an improvement, wouldn't it?
