Before you begin your heart-rate training, there are some things you might want to know regarding your maximum heart rate (HR Max). 

To determine your maximum heart rate a general formula is to subtract your age from 220. It’s important to note that calculating your HR Max this way is only a guide. You may have a higher or lower HR Max, sometimes by as much as 15 to 20 beats per minute. This is why taking a HR max test will give you more precise information to proceed from (you can take a free HR Max test directly in our app)

Generally only elite athletes are concerned about this level of precision. They may also use slightly different calculations that take into account sex differences in target heart rate zones. These differences are so small that most casual athletes don’t need separate calculations for men and women.

Different activities, Different HR Max Tests
In general heart rate is a little lower during cycling compared to running, since we are not supporting our full bodyweight or using as many muscle groups to power the bike forwards. The difference is usually around 5 to 10 beats pr. minute. Keep this in mind when testing yourself.
