If you're a beginner, start by walking 3 days per week for at least 15-20 minutes. Gradually increase the frequency and duration of your walks until you are walking 30-60 minutes per day, most days of the week. To help keep your
walks enjoyable try alternate walking indoors with walking outdoors, watching television during your walks (using a treadmill), or listening to music or a book on tape with headphones. For most people it's not walking they dislike, but becoming bored during the walk. Work walking into your regular routine and make it a priority.
