Treadmills are great for many people, if you do not want to go to a gym or outside due to weather, whether it's too hot too cold or raining cats and dogs; you can simply get on your treadmill and walk or run however long you want. The bigger plus to having a treadmill rather than going for a jog or stroll is that; you do not have to turn and run back, when you are done for that time you are done, just get off the treadmill and go about your day however you wish.
