Target Heart Rate

Karvonen Heart Rate

The Karvonen method of calculating your exercise heart rate is considered the gold standard, benefiting athletes, or people who are looking for weight loss and fitness improvement.

As a person becomes more fit, their heart becomes more efficient at pumping blood to the rest of the body. When resting, the number of beats per minute slows down. The Karvonen calculation, devised by a Scandinavian physiologist, takes this into consideration by introducing a number called the heart rate reserve into the equation — the difference between your maximal heart rate and your resting heart rate.

To find out what your more accurate target heart rate should be while exercising, you will need to determine your resting heart rate. The best time to check your resting rate is just before you get up in the morning after a good night’s sleep. Take the average of two or three mornings’ readings for greater accuracy.

Your age   = maximal heart rate (MHR) 
2. Find your resting heart rate (RHR):
take your pulse one time each day for a minute when you wake up. Do this three days in a row.
Morning 1 
Morning 2 
Morning 3 
3. MHR - RHR = Heart Rate Reserve
- =
4. Heart rate reserve x .60 = minimum heart rate + RHR (resting) = low range
x .6 = + RHR = low range
5. Heart rate reserve x .90 = maximum heart rate + RHR (resting) = high range
x .9 = + RHR = high range
6. Range:
  low beats per minute
  high beats per minute
7. For a 10 second count divide number by 6
  low beats per minute
  high beats per minute
