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.
You should feel a pulsing or tapping against your fingers. Watch the second hand and count the number of pulses you feel in 30 seconds. Double that number to find out your heart rate or pulse for 1 minute. The usual resting pulse for an adult is 60 to 100 beats per minute.To find your resting pulse, count your pulse after you have been sitting or resting quietly for at least 10 minutes.ou should feel a pulsing or tapping against your fingers.
