Exactly how much–or how little–exercise it takes to begin paying dividends has been one of the happy surprises of longevity research. A 2016 study found that elderly people who exercised for just 15 minutes a day, at an intensity level of a brisk walk, had a 22% lower risk of early death compared to people who did no exercise. A 2017 study found that exercising even just two days a week can lower risk for premature death. Researchers from McMaster University in Canada even found that breaking a sweat for just 60 seconds may be enough to improve health and fitness (as long as it’s a tough workout).
