A new formula for exercise? Study suggests 1 hour of activity per 8 hours of sitting

(Washington Post) If you fear you’re doing irreparable damage to your body because your white-collar job keeps you sitting at your desk from 9 to 5, or you regularly spend entire weekends sprawled out on your couch binge-watching Netflix, there’s some good news just out from sports medicine researchers.
According to a study…, all is not lost. You may be able to make up for your increased risk of death due to a sedentary lifestyle by engaging in enough physical activity.
So just how much is enough? The first thing you need to know is that it’s not a fixed number but based on a ratio that depends on the amount of sitting you do daily. If you sit four hours a day, you need to do at least 30 minutes of exercise. An eight-hour work day of sitting means one hour of exercise.
The numbers come from an analysis based on a very large pool of people, about 1 million adults, 45 and older, from the United States, Western Europe and Australia. The findings show a risk reduction — or even elimination — for your risk of death from heart disease, diabetes and some cancers.
