Resting heart rate chart women

Heart rate is measured by the number of times your heart beats in one minute. Your heart rate can give information about how hard your heart is working during a particular activity.

Heart rate can be measured by taking your pulse at your carotid artery on the side of your neck, or at the radial artery on the thumb side of your forearm. Count the number of beats within 60 seconds.

Heart rate is divided into different zones, which can be used to help you monitor the intensity of your activity.

This article discusses different heart rate zones and how to increase your aerobic capacity—your body's ability to use oxygen during exercise.
