Free Heart Rate Zone Calculator – Cardio Training Zones
Heart Rate Zone Calculator
Estimate basic heart rate zones for cardio training. Many fitness websites offer a “heart rate zone calculator” or “target heart rate” tool based on age.
About Target Heart Rate Zones
The calculator uses a common estimate for maximum heart rate (220 minus age) and then shows approximate training zones as percentages of that value. This is often used as a general reference for cardio exercise intensity.
These values are only rough guidelines. People with heart conditions or other health concerns must always speak with a doctor before starting or changing an exercise program.
Frequently Asked Questions
1. Is 220 minus age accurate for everyone?
No. It is only a simple approximation and can be different from your actual maximum heart rate.
2. Do I need to stay exactly in these zones?
No. Heart rate training should be personalised and supervised when necessary. Always follow the advice of your trainer or doctor.
3. Should people with heart problems use this tool?
People with any medical condition should only exercise under professional guidance. This tool is not suitable for medical decision making.
