For a choice of exercise or sport they don't get much easier and cheaper than jogging & running. A total body workout is available just by putting some shoes on, heading out the door and finding a park or route to run in.
The act of running
Invented by humans some years ago for catching prey and escaping danger running is becoming popular again. People are re-discovering the feeling it gives. The confidence and determination during a run and the sense of achievement and euphoria afterwards.
Running is one of the best exercises for improving health and fitness. It involves nearly every major muscle group and greatly improves the cardiovascular (heart) system. For weight loss you'll burn around 130 calories every 10 minutes depending how fast you go.
To begin with...
For those who've been inactive for a long period a slow build up is essential, injuries can easily occur if too much is done too soon. A beginner would do better training by time spent running rather than distance covered. As the weeks go by and fitness improves, you gradually increase that time.
While running is suitable for most there are some who may not get much out of it. For people who are very overweight, running may not be a good first choice activity. There won't be much satisfaction from running for 10 or 20 seconds before having to stop. Cycling or swimming would be a better alternative so some strength and weight loss can be established.
