Maximum Heat Rate is the beats per minute (bpm) when the heart is under maximum stress.

Represented as MHR or HRmax. MHR varies by age. There are three ways to compute your maximum heart rate.

1. 220 – Age This is the most commonly used formula to calculate MaxHR.

2. 207 – (0.7 * Age) This formula is more accurate and precise for people over the age of 40.

3. 211 – (0.64 * Age) This is catered to the set of people who are very active.

Note: the above formula and MaxHR values are for theoretical calculations and references. They don’t take into account the gender or type of activity. For some women the MaxHR is 5-10 beats higher than Men.
