A major new analysis suggests that far more weekly exercise than the current WHO guideline of 150 minutes may deliver dramatically greater protection against heart disease — potentially 560 to 610 minutes per week. But the story is more nuanced than it sounds.
A New Look at Weekly Exercise Needs
For years, the World Health Organization has recommended at least 150 minutes of moderate physical activity per week. It’s a realistic benchmark — one many people still struggle to reach — and it has been widely accepted as the global standard for basic cardiovascular protection.
But a new study from the Macao Polytechnic University, published in the British Journal of Sports Medicine, suggests that this threshold may be only the beginning. According to the researchers, ten hours of movement per week could reduce cardiovascular risk by more than 30 percent.
That’s a bold claim — and it’s based on a very different approach to measuring physical activity.
What the Researchers Did Differently
The study analyzed data from over 17,000 adults in the UK Biobank. Participants wore activity sensors for a week, giving researchers a precise picture of their daily movement. They also completed a cycling test to estimate their VO₂ max, a key indicator of cardiovascular fitness.
Over the next eight years, scientists tracked which participants developed heart-related illnesses. The results were striking:
- 150 minutes/week → 8–9% lower risk of cardiovascular disease
- 560–610 minutes/week → over 30% lower risk
Only 12% of participants achieved the higher activity level — a reminder that such a routine is far from typical.
Why the WHO Guideline Still Matters
Ten hours of exercise per week sounds great on paper, but for most people juggling work, family, and daily responsibilities, it’s simply not realistic.
That’s why the WHO’s 150‑minute recommendation remains essential:
- It’s achievable for a large portion of the population.
- It provides a solid baseline of protection.
- It encourages people to move more without overwhelming them.
Think of 150 minutes as a minimum, not a ceiling.
Fitness Levels Matter
The study also highlights an important nuance:
People with lower baseline fitness may need more movement to achieve the same protective effect as naturally fitter individuals.
This doesn’t mean everyone must aim for ten hours a week. It means that your ideal amount of exercise depends on your current fitness level, lifestyle, and health status.
A Word of Caution
The researchers emphasize that this was an observational study. That means:
- It cannot prove cause and effect.
- It’s possible that the most active participants were already healthier to begin with.
- The sample may not represent the general population.
Still, the findings add weight to a growing body of evidence: more movement is better — up to a point.
So How Much Should You Exercise Each Week?
Here’s a practical way to think about it:
- 150 minutes/week → A strong, evidence‑based minimum
- 300–450 minutes/week → Noticeably greater benefits
- 560–610 minutes/week → Maximum cardiovascular protection observed in the study
A balanced routine might include:
- Moderate workouts like brisk walking or cycling
- Intense sessions like interval training or fast running
- Recovery days to prevent injury and support long‑term progress
Every minute counts — and consistency matters more than perfection.
The Bottom Line
You don’t need to become a marathon runner to protect your heart. But if you want to unlock additional health benefits, adding more movement to your week is a powerful, evidence‑supported strategy.
Whether you choose 150 minutes or 600, the most important thing is simple:
Move more than you did yesterday. Your heart will thank you.
