(MHR) = Maximum Heart Rate
(THR) = Target Heart Rate
220 - age = maximum heart rate (MHR).
MHR x .60 = 60% of your maximum heart rate.
MHR x .75 = 75% of your maximum heart rate.
For example, if you are 30 years old, your calculations will be as follows: 220 - 30 = 190
190 x .60 = 114 (low end or 60% of MHR)
190 x .75 = 142 (high end or 75% of MHR)
30
