The optimal heart rate for exercise is between 60 and 75% of the maximum heart rate for fat burning.
Maximum Heart Rate: For the first calculation, subtract your age from 220.
Target Zone: For example, if he is 20 years old, 200 Then calculate 60 percent of 200 and then 75 percent of 200, which is in order 120 and 150 So your heart rate for burning fat should be between 120 and 150.
Of course, if you use Karvonen's method, it is more accurate and a bit more complicated Some of these smart watches always do these calculations for you and are very good in this sense
