How much cardio a week for a longer, healthier life: 150 to 300 minutes moderate, how to split it, and how to manage Malaysian heat and haze.
For longevity, aim for 150 to 300 minutes of moderate cardio a week, or 75 to 150 minutes of vigorous cardio, plus strength training on at least two days. That is the WHO range, and it matches the point where most of the survival benefit appears. The largest gain comes from going from nothing to something, so start with what you can sustain.
Where the numbers come from
The WHO 2020 guidelines recommend 150 to 300 minutes of moderate-intensity or 75 to 150 minutes of vigorous-intensity aerobic activity a week for adults, including older adults, with additional benefits above that range. Moderate means breathing harder but still able to talk. Vigorous means you can say only a few words at a time.
Two large pooled analyses show the dose-response curve:
- Arem et al. pooled six US and European cohorts and found that people doing about the minimum recommended amount had around 20% to 30% lower mortality than inactive people, and the lowest risk appeared at around three to five times the minimum, about 30 to 40% lower. Doing more than 10 times the minimum was not linked with harm.
- Moore et al. estimated that the minimum recommended level (about 150 minutes of moderate activity a week) was associated with about 3.4 extra years of life expectancy compared with no leisure-time activity. A small amount, under about 75 minutes of moderate activity a week, was linked with about 1.8 years, and the highest levels with about 4.5 years.
These are observational data, so they show association, but they agree with the guidelines and with trial evidence on heart and metabolic health. Cardiorespiratory fitness itself is also a strong predictor of survival. Mandsager et al. found that people with low fitness had much higher mortality than those with high fitness, with the gradient continuing into elite levels. See VO2 max and lifespan.
What counts
| Intensity | How it feels | Examples | Counts as |
|---|---|---|---|
| Moderate | Faster breathing, can talk | Brisk walking at about 100 steps a minute, easy cycling, water aerobics, senamrobik | 1 minute |
| Vigorous | Can only say a few words | Running, fast cycling, hill walking, intervals | About 2 minutes of moderate |

How to split the week
- Most-days pattern. A brisk 30-minute walk five days a week gives 150 minutes. See walking for longevity.
- Busy pattern. Three sessions of 45 to 60 minutes, such as cycling, swimming or a long walk.
- Mixed pattern. About 150 to 180 minutes of easy Zone 2 cardio, plus one harder session such as the Norwegian 4x4 once you have a base and your doctor agrees. See weekly Zone 2 schedule.
- Starter pattern. If you are inactive, begin with 10 minutes a day and add 5 minutes a week. Even 60 to 90 minutes a week is much better than none.
Ten-minute bouts count towards the total, so you can break the day up.
Fitting cardio around Malaysian heat and haze
- Walk before 8 am or after 6 pm, or use shaded parks.
- Use malls and air-conditioned corridors on hot or hazy days. See indoor exercise for hot and hazy days and mall walking.
- Drink water before and during exercise. See staying hydrated in tropical heat.
- Allow a few weeks to acclimatise, and ease the pace when it is humid. See exercising in Malaysia’s heat and humidity.
- Skip hard outdoor exercise on bad haze days. See should you exercise during the haze.
Cardio does not replace strength
Cardio builds the heart and stamina but not much muscle or bone. Add two strength sessions a week, and balance work if you are older. See strength vs cardio for longevity and strength training for longevity.
Safety
Build up gradually, increasing weekly volume by no more than about 10% to 20% at a time. See a doctor before vigorous exercise if you are inactive and over 40, or if you have heart disease, diabetes, high blood pressure or chest pain. Stop and seek care for chest pain, fainting, severe breathlessness or irregular palpitations. See when to get medical clearance before exercise.
How to gauge intensity
- Talk test. Moderate: you can talk but not sing. Vigorous: you can say only a few words.
- Effort scale. On a 0 to 10 scale, moderate is 5 to 6 and vigorous is 7 to 8.
- Heart rate. The formula 220 minus age is only a rough estimate and can be off by 10 to 20 beats, so use it as a guide at most. Use the heart rate zones tool. Blood pressure tablets such as beta-blockers lower heart rate, so rely on the talk test.
Sample weeks by starting level
| Level | Weekly cardio | Example |
|---|---|---|
| Starting out | 60 to 90 minutes moderate | Six 10 to 15 minute brisk walks |
| Building | 150 minutes moderate | Five 30-minute walks or cycles |
| Established | 180 to 240 minutes mostly easy, plus one harder session | Three Zone 2 sessions of 45 to 60 minutes, one 4x4 interval session, one long walk |
People with heart disease, uncontrolled blood pressure or diabetes complications should start with medical advice, and some will benefit from supervised cardiac rehab. See cardiac rehab: rebuilding fitness and exercise for high blood pressure.
Key takeaways
- Aim for 150 to 300 minutes of moderate cardio, or 75 to 150 of vigorous, each week.
- The biggest benefit comes from moving from inactive to somewhat active, and higher amounts add smaller gains.
- Split the minutes however suits your week, with a base of easy cardio plus one hard session if you are cleared.
- Add two strength sessions a week. Cardio does not replace them.
- Plan around Malaysian heat and haze, and build up gradually.
