How Much Exercise A Week Is Best For Health Span & Life Span?

No surprise here: Exercise is phenomenally good for us. It improves our mood (hello, endorphins), boosts our brain function, keeps our bodies strong, and improves our overall quality and length of life1.

Researchers were interested to see how the current physical activity guidelines for Americans affected participants' mortality risk. These recommendations call for 150 to 300 minutes of MPA per week, 75 to 150 minutes of VPA per week, or some equivalent combination of them both.

They found that exercise is even more closely tied to longevity than you might think. When researchers looked at the hazard ratio—the risk of dying from a variety of common age-associated diseases—they found the current guidelines underestimate just how valuable additional exercise could be.

There are several lifestyle considerations to keep in mind when thinking about longevity. Our diet, sleep, social connections, stress levels, and physical activity all play a part in how long we live—and even more importantly, how long we stay feeling healthy.

The good news is that starting with healthy habits today will set us up for success with each passing year and decade.

And as far as exercise goes, it looks like the optimal amount of exercise for longevity is approaching 2.5 to five hours of vigorous activity every week or five to 10 hours of moderate exercise per week. For optimal fitness, an equivalent combination of both is a good balance.

If you're already exercising plenty, consider this one more reason to stay motivated. If not, thinking about ways to sneak in just a bit more moderate activity daily can pay dividends. Just 45 minutes per day can deliver maximum longevity benefits!

And if you're in an exercise rut or feeling burnt out on one type of activity, consider this your permission slip to mix it up and try some new things. This primer on zone 2 cardio can help you get started.
