Gina Kolata also wrote a book claiming that people aren't fit because they exercise; rather that people exercise because they are fit. By that logic, Americans don't exercise because they aren't fit.
Studies also say that people sleep increasingly little... less than they need to, supposedly, at present. Why wouldn't people sleep if they "had time"? Therefore my working theory is that people (who aren't unemployed) don't really have that much of what they consider free time. Show me data on hours spent at work, hours spent preparing and eating food, hours spent commuting, and time for other required incidental activities like paying the bills, going to parent-teacher conferences, and fueling and repairing their vehicle. I think most people will tell you they feel they don't have sufficient fully unstructured time. And in that situation, since most Americans don't get involved in activities so they can do things that are fun rather than think about it as exercise (which frankly sounds dreadful to them), they do other things that are fun. Which for most is probably an adult beverage and ass time in front of the television, which can be a nice respite from the stress and illogic of many modern 'murcan workplaces.
I'd have never thought of this angle until once to someone I suggested that I actually enjoyed spending time running and jumping and striking various types of balls and riding bicycles as quickly as possible. As soon as someone says "Oh, you want an exercise lifestyle" you know they just don't understand the active lifestyle or have any sense of physical culture.
Yes this is a problem. I agree that it is obscene for healthy capable adults to enroll in a walking class. I feel the same way about able-bodied people walking a 10k and proclaiming that it is a big effort. We have a women-only mini marathon here in Dublin and thousands of women walk it after 'training' for it during the winter! I believe everyone should be able to walk 10k effortlessly and the fact that some act as if they have completed an endurance event is a sad reflection of the fitness levels in the population. And they really annoy me during the 10k because they block slow runners like me and we have to zig zag our way around them! As to why people don't exercise enough, I think you need to really exert yourself to feel better. I can walk for hours but I don't get the endorphin high that I get from 30 mins high intensity work. When people don't find that exercise gives them an immediate noticeable effect they probably stop. It is the age of instant gratification!

Updating the message to get people moving Gina Kolata 11/22/2012 3:00 AM
Rod Dishman, director of the exercise psychology laboratory at the University of Georgia, is annoyed when students enroll in one of the fitness classes offered at his university. Because it’s a class in walking.
“It is a sin for a healthy, capable young adult to enroll in a walking class," he said. “It is obscene. What they are getting credit for is avoiding making any effort."
And therein lies a problem, Dishman and other researchers say. The public health message about exercise is that any amount is good and that walking is just fine. Everyone has been told, repeatedly, that regular exercise improves health and makes people feel better, happier, more energetic. Nearly all Americans say they have heard those messages. They know that exercise is good for them and that they should do it.
Yet they do not.
About 40 percent of Americans report that they never exercise, a figure that has remained steady for decades. They will not even do the easy stuff. In studies of moderate exercise to help prevent diabetes, for example, investigators had to go to great lengths just to keep subjects in a walking program.
Now, with more recent studies using accelerometers that measure actual movement rather than relying on self-reports, the data are even more dismal. Only 3.5 percent of Americans between ages 18 and 59 do the minimum amount of physical activity recommended by the Department of Health and Human Services: 150 minutes a week of moderate activity. Among those over age 60, the percentage is even lower: 2.5 percent.
“It is stunning," said Panteleimon Ekkekakis, an exercise researcher at Iowa State University.
If Americans know exercise is so good for them, why don’t they take the message to heart as they did the exhortations against smoking? And if exercise makes people feel so good, why don’t they just do it?
Maybe, some researchers say, the problem is the message. It obviously has not had much of an effect. The idea now is to make use of tools that psychologists have developed to assess people’s moods during exercise, asking how good or bad it feels as the intensity varies.
In a series of studies, Ekkekakis and his colleagues found that as exercise intensity increased to the point where a person was on the verge of breathing so hard that it was difficult to talk — the so-called ventilatory threshold — people had different reactions. Some say they felt more and more pleasure, while others felt less. Beyond the ventilatory threshold, though, most felt bad. It’s complicated, though. A hard workout for one person can be ridiculously easy for another.
At one extreme are acutely sedentary people.
“As soon as they get up and take a few steps, they are above their ventilatory threshold," Ekkekakis said.
At the other extreme are athletes who cannot reach their ventilatory thresholds until their hearts are beating at nearly the maximum rate.
Even within fitness levels, there are individual variations. Some people actually feel their best when they surpass their ventilatory threshold.
It is not at all clear what is going on in the brain — why at some level of intensity a workout starts to feel good. Nor, Dishman said, is it known why a long endurance workout can feel good in a different way than a short workout with intense bursts of effort.
But Ekkekakis has discovered a few clues. He borrowed from Daniel Kahneman, the Princeton psychologist whose research has found that people remember two parts of an experience: the peak, when the feeling was most intense, and the end.
Ekkekakis and his colleagues recruited volunteers for a study in which subjects exercised for 20 minutes at a level they reported was unpleasant. In one session, the subjects had a five-minute cooling-down period afterward, which immediately changed their moods because it felt pleasant. In the other session, the subjects stopped exercising, without a cool-down.
A week later, the researchers asked their subjects, “Which of the two workouts would you repeat?"
“At a ratio of 2-to-1, they chose the one with the pleasant end," Ekkekakis said. “But they cannot tell you why."
There may be a public health lesson there, researchers say.
Simply giving people an exercise prescription, like walking for 20 minutes a day, five days a week, is clearly not working. Nor are programs that claim very intense, very short bouts of exercise are all that is needed.
To encourage exercise, perhaps people should be told to find an exercise, and an intensity level, that makes them feel good, Ekkekakis said.
