In praise of ... pedometers - The Guardian 22nd January 2008

One of the smallest, cheapest, oldest and most cost-effective gadgets of them all, it rarely gets the kind of coverage it deserves. The pedometer, which simply records the number of steps you take as you walk, can be purchased for less than £5 but often has a disproportionate and beneficial effect on health. A recent survey, published in the Journal of the American Medical Association, found that use of a pedometer was associated with significant increases in physical activity and decreases in body mass index and blood pressure. It is not a miracle worker but people with pedometers tend to be more conscious of their daily exercise and, when they drop below the 10,000 steps a day recommended for weight control, are more likely to do something about it.
