Heart Rate Zone: Your Questions Answered
These are the questions people ask most often about heart rate zone. Each answer is short; follow the links for the full detail.
What does a heart rate zone calculation tell me?
Shows heart-rate training zones from your age.
What is the formula?
Max HR = 220 − age; zones are percentages of max.
What do I need to enter?
Age.
Is this a medical assessment?
No. These are general estimates. Speak to a doctor or polyclinic for advice about your health.
Can you show an example?
For example, with these inputs:
- Age: 35
the calculator returns:
- Maximum heart rate: 185 bpm
- Zone 2 (fat burn): 111–130 bpm
- Zone 3 (aerobic): 130–148 bpm
- Zone 4 (threshold): 148–167 bpm
Any tips?
- Track trends over weeks rather than reacting to a single reading.
- Asian BMI cut-offs are lower than WHO's, so a 'normal' international BMI can still mean moderate risk.
- See a healthcare professional before big changes to diet or exercise, especially if you have a medical condition.
Background
Any health calculator gives a general estimate. If a result worries you, or you are pregnant, managing a chronic condition or planning a big change in diet or exercise, speak to a doctor, polyclinic or dietitian.
Singapore's tropical climate means you lose more fluid through sweat, even when you are not exercising. Thirst, urine colour and how you feel are good guides, and needs rise during outdoor activity or heat waves.
Programmes such as the National Steps Challenge and the Healthy 365 app have made tracking activity common. Turning those numbers into distance, pace or calories helps set realistic goals for events like IPPT or a 10 km run.
