Monitored heart rate can be an effective motivator. Without an electronic monitor, heart rate is easiest to locate at the carotid artery, on the side of the neck rather than the wrist. Gently pressing the area with index and middle fingers, count each beat for at least 15 seconds, and multiply the number of beats by a number so that it corresponds to one minute. (For x beats in 15 seconds, multiply x by 4.)

Working heart rate, which could be anywhere from 140 - 190 beats per minute, should be monitored to make sure that it stays at a safe level. After strenuous work, heart rate should soon recover to about 120 BPM or less. Below is a chart of the appropriate ranges of working heart rate corresponding to age and resting heart rate.
