The heart rate calculator finds the pulse you should aim for when performing an exercise of a certain intensity. Read on if you'd like to know how to calculate the heart rate for your physical activities.
You might want to check out your heart rate zones for the optimal cardio exercise with our target heart rate calculator or estimate the maximum heart rate for your age.
How to calculate heart rate?
The formula used for the heart rate calculation looks like this:
HR = resting_HR + intensity% * (220 - resting_HR - age)
The values you need to input are:
resting_HR- your heart rate at rest - it's best to measure it right after you wake up or after sitting or lying down in a relaxed state for a longer period;
intensity%- the intensity of exercise you're aiming - read on to find out more about heart rate zones;
age- your age in years.
What are heart rate zones?
When you start any physical activity, its intensity is soon reflected by your heart rate. The range from a moderate acceleration of your pulse to the maximum capacity is divided into heart rate zones. To put it simply, they are the levels of intensity of your exercise.

- 50 - 60% - Moderate exercise - requires a medium amount of effort.
- 60 - 70% - Fat burning zone - optimal heart range for burning fatty tissue.
- 70 - 80% - Aerobic range - intense training, leading to muscle gain and cardiovascular improvement.
- 80 - 90% - Anaerobic range - very intense training, causing the metabolism to switch to mechanisms producing lactate.
- 90 - 100% - "Red line" range - maximal effort, that can be sustained only for a short period.
Depending on your goals, you can aim for different ranges of exercise intensity. Calculate the target heart rate and remember to stay hydrated :)
