Walking over 3 miles an hour is classed as moderate exercise. 2.5 hours every week, so most experts suggest 30 minutes a day, five days a week or if you prefer, 20 minutes every day. If you can manage 4.5 miles per hour or uphill, thats vigorous exercise similar to light running or cycling. At this intensity, an hour and fifteen minutes a week is sufficient.
