Check your pulse recovery rate – If your pulse is over 100 bpm five minutes after you stop exercising, or if it’s higher than normal the morning after exer- cising, your exertion may have been too strenuous for your current fitness level. Rest and reduce the intensity next time.
(MHR) = Maximum Heart Rate
(THR) = Target Heart Rate
220 - age = maximum heart rate (MHZ)
MHZ x .60 = 60% of your maximum heart rate. MHZ 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 MHZ)
190 x .75 = 142 (high end or 75% of MHZ)
