While regularly exercising over the course of decades is a great way to live longer, a US study suggests that even people who don’t start working out until middle-age may see similar longevity benefits.
To help people live longer, national guidelines for physical fitness recommend that adults get at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous exercise each week. But much of the evidence behind these recommendations has looked at exercise at only one point in time, leaving a murky picture of how lifelong exercise habits might impact longevity, researchers note in JAMA Network Open.
