As a rule of thumb: 220 - Your Age. This calculator, however, uses the formula 205.8 - (0.685 x Your Age). Studies have shown that this is a better way to calculate your maximum heart rate.
To calculate your Heart Rate Reserve, simply subtract Your Resting Heart Rate from your Maximum Heart Rate.
It is recommended to measure your heart rate 4-5 days in a row straight before getting up from bed in the morning and taking the average of your measurements.
