Exercise and Performance
Exercise has some of the strongest evidence of any habit linked to longer life. In a pooled analysis of 661,137 adults, people who did one to two times the recommended minimum of leisure-time activity had a 31% lower risk of death than inactive people. The benefit levelled off at three to five times the minimum (39% lower), with no sign of harm at ten times or more.1
Fitness and strength matter too. Among 122,007 adults who had treadmill tests, lower cardiorespiratory fitness was linked to higher long-term mortality with no observed upper limit of benefit.2 In 139,691 people across 17 countries, each 5 kg of lower grip strength was linked to a 16% higher risk of death, and grip strength predicted all-cause and cardiovascular mortality better than systolic blood pressure.3 In a meta-analysis of cohort studies, muscle-strengthening activity was associated with a 10–17% lower risk of death, cardiovascular disease, cancer and diabetes, with the largest reductions in death, heart disease and cancer at about 30 to 60 minutes a week.4
These are observational findings; whether building strength itself lowers mortality is still being tested.3 The articles below turn the evidence into a weekly routine and test the common myths.
