Terrific article on the benefits of exercise and the commitment required to make a difference. Here's one great story from the article:
Then there’s Charles Reilly, a federal prosecutor in Manhattan and a marathon runner who took a 10-year hiatus from the sport when he joined his local school board. He just did not have time to exercise, he said. Along with exercising less, he ate more. Soon he ballooned from 159 pounds to 282. “It came on gradually, but it came on,” Mr. Reilly said of the weight.
On April 18, 2005, he had his last school board meeting — he’d decided not to run for any more terms. Eight days later, he went out for a run.
“After half a mile, I had to stop and walk,” Mr. Reilly said. But he kept trying. A month later, he could run three miles without stopping. After three or four months, he says, he could run for five miles. By the end of 2006, he ran 10 miles. In the meantime, he also changed his diet. “My goal was to lose 100 pounds,” Mr. Reilly said. He did it, hitting his goal on Feb. 3, 2007, in a little over 21 months.
