There are different ways to calculate your target heart rate zone, but the Karvonen Method is one of the most effective because it factors in your resting heart rate. Here's how to calculate your target heart rate zone using the Karvonen Method: 1. Measure your resting heart rate when you first wake up. You can do this by taking your pulse for one minute while still in bed. To take your pulse, place two fingertips (not a thumb) on either the radial (on your wrist, at the base of your thumb) or carotid (neck, next to your larynx) pulse site.
To check your pulse at your wrist, place two fingers between the bone and the tendon over your radial artery â which is located on the thumb side of your wrist. When you feel your pulse, count the number of beats in 15 seconds. Multiply this number by 4 to calculate your beats a minute.Keep in mind that many factors can influence heart rate, including: 1  Activity level. 2  Fitness level. 3  Air temperature. 4  Body position (standing up or lying down, for example). 5  Emotions. 6  Body size.hen you feel your pulse, count the number of beats in 15 seconds.
