Do you want to get the most out of those 35 minutes on the treadmill, or any kind of cardio exercise? You maximize the benefits of cardiovascular activity when you exercise in the zone of your target heart rate(THR). In general terms, your THR is 60-80% of your maximum heart rate. The Karvonen Method of calculating THR is one of the most effective methods to determine target heart rate because it takes into account resting heart rate. Here's how to find your THR.
your age from 220. This is your maximum heart rate (HRmax). For
example, the HRmax for a 40-year-old would be
220 - 40 = 180.
your RHR from your HRmax. This is your heart rate reserve
(HRmaxRESERVE). For example,
HRmaxRESERVE = 180 - 63 = 117
(133 + 157) / 2 = 145 (You can get the same result by simply multiplying HRmaxRESERVE by 0.70 and adding to it RHR).
