A lot of people are still under the impression that spending hours on the treadmill will help lose body fat, despite plenty of research stating the opposite.
A study published by Williams and Woods (2006) using almost 13,000 habitual runners observed they all tended to get fatter every year, even those who ran more than 68 km a week!
One of the many problems with long distance cardio is the body adapts too quickly to the stimulus placed upon it and is regarded useless after 6-8 weeks.
If you're looking at improving your body composition my advice would be, ditch the treadmill and start lifting some weight.
