What is my resting heart rate?
Calculating Target Heart Rate
The highest, safe heart rate you should theoretically be able to have your heart beat at is known as the Maximum Heart Rate (MHR).
Determine your Maximum Heart Rate (MHR) by subtracting your age from 220.
220 - age = MHR
We will use a 20 year-old with a resting heart rate of 60 beats per minute (BMP) for our example:
220-20 = 200 BPM
Heart Rate ReserveSubtract your Resting Heart Rate (RHR) from your Maximum Heart Rate (MHR). This gives your Heart Rate Reserve (HRmax Reserve).
MHR - RHR = HRmax Reserve
Using the 20 year-old with a resting heart rate of 60 beats per minute (BMP) for our example:
200 – 60 = 140
Lower End of THR Zone
To get the lower end of your target heart rate (50%), multiply your Heart Rate Reserve by .50 and then add your Resting Heart Rate to it.
(HRmax Reserve × 0.50) + RHR = low end of zone
Using the 20 year-old with a resting heart rate of 60 beats per minute (BMP) for our example:
(140 X 0.50) + 60 = 130 BPM
Upper limit of your THRTo get the higher end of your target heart rate zone (85%), multiply your Heart Rate Reserve from step 2 by 0.85, and add your Resting Heart Rate to it.
(HRmax Reserve × 0.85) + RHR = high end of zone
Using the 20 year-old with a resting heart rate of 60 beats per minute (BMP) for our example:
(140 X 0.85) + 60 = 179 BPM
Rest and Recovery After exercise, your heart rate should go back down. This is called your recovery heart rate (heart rate immediately after exercise).
Five minutes after you stop exercising, your heart rate should be 120 beats per minute or less.
Ten minutes after you stop exercising, your heart rate should be 100 beats per minute or less.
