This article's conclusion aren't adding up.<p>1. Physical exercise won't help but getting up from your seat does. The former is a super set of the latter. You could argue that you only get up once for physical exercise but you can't totally discount the muscle movements during that 30-60 min period.<p>2. They assume that those who are sitting for long hours are obese. As far as I've seen, a large percentage of engineers who sit in front of the computer all day aren't all obese.<p>Maybe the article wants to focus on a small section of couch potatoes and trying to sensationalize sitting.
