Difficulty: Moderately Easy
Step1
Determine your resting heart rate. It is best to do this upon waking. You can do this by counting your pulse for one minute while still in bed. Do this 3 days in a row and then add the totals and divide by 3 for an average. This is your resting heart rate (RHR)
Step2
Find your maximum heart rate and heart rate reserve.
To do this, subtract your age from 220. That is your maximum heart rate (MHR)
Step3
Subtract your RHR from your MHR and this is your heart rate reserve. Calculate your
Target Heart Rate using an online calculator.
