Get Your Heart Rate Zone Below

Enter your Age, Resting Heart Rate and Maximum Heart Rate (If Known) then click Calculate
Age and resting heart  rate are required fields.  If maximum heart rate is entered that number is used in the calculations rather than age.  For new calculations you must clear maximum heart rate.

Formulas Used For Running

Max Heart Rate (Male) = 214 - Age * 0.8 (Calculated)
Max Heart Rate (Female) = 209 - Age * 0.7

Formulas Used  For Swimming

Max Heart Rate (Male) = 198 - Age * 0.8
Max Heart Rate (Female) = 193 - Age * 0.7

Cycling, Rowing heart rates would be slightly below Running and above Swimming

It is better and more accurate to calculate your maximum heart rate for the specific sport you are training in.

Example for 50%

50% Heart Rate =   (Max Heart Rate - Resting Heart Rate) * 50%
