In order to exercise 300 calories per day, do at least one of the following:
Walk 4 miles per day
10,000 steps per day
30 minutes of aerobic exercise a day
You don't have to do it all at once. When you haven't been exercising regularly, you also have to develop a level of basic fitness that has been missing, so you won't want to start at these goals, but work up to them.
