A comprehensive new study has revealed that performing two to four times the amount of exercise currently recommended by health authorities may slash the risk of early death from any cause by up to 31%. The findings underline the profound benefits of staying physically active—even beyond what health guidelines stipulate—regardless of exercise intensity.
Researchers tracked more than 100,000 U.S. adults over three decades, using data from the long-running Nurses’ Health Study and Health Professionals Follow-Up Study. Participants regularly reported their weekly exercise habits, which the team translated into standardized measures of moderate and vigorous activity.
Key recommendations from the American Heart Association advise at least 150 minutes of moderate activity or 75 minutes of vigorous activity per week. This research found that meeting these guidelines already reduced the risk of death by about 20%. However, those who doubled or even quadrupled their activity—achieving 300 to 600 minutes of moderate exercise or 150 to 300 minutes of vigorous activity per week—reduced their risk even further, by 26% to 31%.
The research confirms that both brisk walks and intense workouts offer protective benefits, and these advantages “stack” even for those already active. Notably, the risk reduction plateaued at these higher levels, meaning pushing beyond this range did not provide additional life expectancy gains—but also showed no harm. Even individuals reporting high activity levels, such as more than 600 minutes of moderate or 300 minutes of vigorous activity per week, did not show adverse effects on heart health.
This robust study allays long-held concerns about the potential risks of extreme endurance exercise, pointing instead towards a consistent message: more movement, up to a reasonable upper limit, leads to longer, healthier lives. These positive results spanned all age groups and body types, though the greatest benefits were observed in leaner participants.
Experts recommend incorporating a mix of activities—such as several brisk walks, resistance training, and cycling—while reminding individuals to consult a healthcare professional before greatly increasing physical activity, especially those with preexisting conditions.
