问题    You want to get healthy. You know you need to exercise more. But you are not ready to do intense physical activities. Don’t worry! The best thing for most of us may be to just go for n walk.
   Yes, walk. At a reasonably vigorous clip (five to six kilometers per hour) for half an hour or so, maybe five or six times a week. You may not feel the benefits all at once, but the evidence suggests that over the long term, a regular walking routine can do you good.
   Walking, in fact, may be the perfect exercise. For starters, it’s one of the safest things you can do with your body. It’s much easier on the knees than running and doesn’t trigger side effects.
   Regular physical activity is probably as close to a magic bullet as we will come in modem medicine, If everyone were to walk briskly for 30 minutes every day, we could cut the incidence of many chronic diseases by 30 to 40 per cent.
   Walking is also a great way to lose body fat, so even if you don’t 10se any weight, your body will have a healthier composition. Most people find they have to walk at least an hour a day to shed kilo.
