ON a recent Thursday evening at the Bon Vivant Diner in Lower Manhattan, three round-bodied women sat at a booth, gabbing happily about warrior poses and downward-facing dogs, when they were interrupted by a heavyset woman in the adjacent booth.
“Excuse me, are you talking about a yoga class?” she asked.
The three women, Cynthia Ayers, Beth Garner and Bridget Clark, told her about their class, Buddha Body Yoga, and gave her a slip of paper with the Web address.

Exercise is known to have many beneficial effects on health, including on the body’s sensitivity to insulin. “Get more exercise” is often among the first recommendations given by doctors to people at risk of diabetes.

Over-eating, not a lack of exercise, is to blame for the American obesity epidemic, a new study claimed Friday, warning that physical activity could not fully compensate for excess calories.
“There is no evidence that a marked reduction in physical activity has been a contributor to this epidemic in the United States,” study leader Boyd Swinburn told AFP on the sidelines of an international obesity conference in Amsterdam, where the research was unveiled.
“The increase in energy intake… virtually explained all of the weight gain.”

“If your goal is to finish, you just need to skate enough so that you can cover the distance. If your goal is to be faster, you have to train.”
There are training programs everywhere — in magazines, books, on the Internet. But eventually, exercise physiologists say, most people need guidance from a group with experienced coaches, like the one Mr. Gordon joined, or from personal coaches.
Training, though, can require such a commitment over so many years that many drop out. Not Mr. Gordon, who loves to train. And that love …

New research from the University of Illinois suggests that weight-loss campaigns that promote exercise may actually cause people to eat more.People who viewed posters suggesting that they “join a gym” or “take a walk” ate more food after looking at the posters than people who saw similarly designed posters prompting them to “make friends” or “be in a group,” the researchers found.

U.S. kids are not only too heavy; they’re also out of shape, according to a new study of 5th and 7th grade students in Georgia.
Half didn’t reach minimum standards for healthy aerobic fitness, Dr. Kenneth E. Powell, a physician in private practice, and his colleagues found, while nearly a quarter didn’t make the grade in terms of muscle fitness, endurance or flexibility.
Powell and his team determined body mass index (BMI) and tested fitness and physical activity levels of 5,248 students from 93 schools across Georgia.
They found that 30 percent of …
