5. Just a bit of exercise will do. It is important though to get some exercise every
day especially if you are in a job where you sit down all day. A half-an-hour walk a day will do. Of course more exercise is always better but never feel bad if you can't get yourself to do it. If you just take that walk for at least half an hour each day you'll be fine. Stretching your muscles is also good, it makes you more conscious of your body.
