Still, the idea that exercising for just 10 minutes a week may be enough to increase your lifespan is novel. It’s also somewhat 27 , since the federal physical activity guidelines recommend getting at least 75 minutes of vigorous exercise or 150 minutes of 28 exercise each week.
The study was based on data from more than 88,000 U.S. adults who 29 in the National Health Interview Survey between 1997 and 2008.

recommended by the federal government had a 46% lower 32 of death than the least active group.
