One of the best things you can do when you start to walk is to keep a walking log/diary. Recording the time of day is important as you might find you are happier walking at a particular time of the day. Record the distance if you have a pedometer that tells you but it is just as good to record the number of steps.
Record whether you strolled, walked at a moderate pace or use a pedometer that tells you your walking speed. Don’t be discouraged if you are walking slowly it is still very good for you.
