244 A.3 Figure Out Your Target Heart Rate! To get the maximum benefit from exercise, it is best to work at a pre-determined target heart rate. A.3.1 Taking your Pulse The pulse is most commonly taken either at the carotid artery on the neck or at the wrist. Use your index finger and middle finger to locate your pulse (never use your thumb). Use a very light touch and avoid pressing too hard. You may use a 6 or 10 second pulse check, then multiply by the appropriate number (10 or 6 respectively) to get a 60 second count. A.3.2 Maximum heart rate This heart rate generally declines with age from about 220 beats per minute in childhood to about 160 beats per minute at age 60. This fall in heart rate is fairly linear, decreasing by approximately 1 beat per minute per year. There is no strong evidence to suggest that training influences the decline in maximal heart rate. It should be remembered that individuals <strong>of</strong> the same age might have quite different maximal heart rates. Therefore it is more accurate to calculate this value by undergoing a stress test than by using an agerelated formula. On the other hand, resting heart rate is greatly influenced by endurance training.
