Are people hard-wired to hate exercise?

Recent scientific studies suggest that there might be more than laziness when it comes to people who hate exercise.

"When it comes to exercise, many people seem to fall into two distinct camps: those who love a vigorous, sweat-soaked workout and those who view it as a form of torment.

"With hopes of getting more people up and moving, scientists are looking at the body's biological and chemical processes for clues to understanding what's behind differing attitudes toward exercise. That could mean there are factors beyond motivation and discipline to explain why some people enjoy exercising and others don't.

"One finding so far: How people interpret their body's sensations during and after exercise plays a large role in whether they enjoy it. Also, researchers at Iowa State University found that people's physical capacity could be much lower than many realize, so many people push beyond their limits without realizing it. For example, for sedentary people, just cooking dinner could count as exercise and they need to build up to even walking, the researchers found."
