Do Pushups This Many Times Per Week

The research: Adults 65 and older who strength-trained twice a week were 46 percent less likely to die over the course of a 15-year study compared with those who didn't work their muscles that often. Previous research in The American Journal of Medicine found that muscle mass was actually a better predictor of longevity than individuals' body mass index (BMI). These studies show association, not causation, so experts aren't sure how muscle mass might translate to a longer life, but the results are a pretty persuasive reason to pick up some dumbbells or drop and give yourself 20 (or—who are we kidding?—10).
