Keeping a record of how many steps you take, the distance you walk and how long it takes can help you see where you started from and serve as a source of inspiration. Just think how good you'll feel when you see how many miles you've walked each week, month or year.
Record these numbers in a walking journal or log them in a spreadsheet
or a physical activity app. Another option is to use an electronic
device — such as a pedometer — to calculate steps and distance.
