The exercise guidelines may be far too low
The standard advice of 150 minutes of exercise per week may be seriously undershooting the mark. New epidemiological evidence points to around 600 minutes per week as the level where real protection against age-related disease kicks in.
Health authorities across the world recommend 150 minutes of moderate to vigorous physical activity per week. It sounds manageable, but the researchers argue this figure reflects what people are willing to do rather than what the body actually needs.
The underlying logic is evolutionary. Humans evolved in environments demanding far greater daily movement than is typical in wealthy, industrialised countries today. Cars, desk jobs and household appliances have stripped most physical effort from daily life. The result is a population operating well below its biological baseline for activity.
Cardiovascular disease as the measuring stick
The study focuses on cardiovascular disease, the leading cause of death in ageing populations. Higher levels of activity reduce systemic inflammation, improve insulin sensitivity (how effectively cells respond to insulin) and keep blood vessels more elastic. These benefits accumulate with increasing movement, with the curve not flattening until around 600 minutes per week.
Epidemiological studies follow large populations over time and compare their movement habits with health outcomes. The design has limitations: people who exercise more often live healthier lives in other ways too. But the consistency across multiple studies makes the association hard to dismiss.
What this means in practice
Six hundred minutes a week works out to roughly 85 minutes a day. That does not have to mean structured sport. Brisk walking, cycling to work and gardening all count. The message is not that 150 minutes is harmful, but that it should be treated as a floor, not a target.
For anyone interested in a longer healthspan, this research makes a clear case for deliberately raising the bar. Not as an obligation, but as an informed choice.
