The study found the group that was almost completely sedentary had a much higher risk of death than the other groups when compared to even the group that did just a little bit of exercise. The article quotes one of the researchers as saying “you don’t have to be a triathlete in the way high end of the scale. Just get out of that least-fit group.”

The difference in physical activity between the least-fit group and the second-least-fit group was small – not much more than and extra half-hour of walking per week. It turns out that 30 minutes of exercise each week could add years to your life. Those in the least-fit group were twice as likely to die of heart disease than the second-least-fit-group. The article again, quote one researcher as saying “It’s not like there were a lot more diabetics or a lot more smokers, or anything like that, that may explain higher mortality in the least-fit group – we notice the one difference that stood out for us was the second-least-fit group was more physically active than the least-fit group.”

Participants in the most-fit group were 4 times less likely to die from heart disease than the least fit group. This group exercised roughly twice as much as the least-fit group or 1 hour per week.

To put this in perspective; if you walk for 10 minutes 3 times per week you can cut your risk of dying from heart disease be 50%!!!!
