To calculate your target training heart rate, you need to know your resting heart rate. Resting heart rate is the number of times your heart beats per minute when it's at rest. The best time to find your resting heart rate is in the morning after a good night's sleep and before you get out of bed. Typically, an adult’s resting heart rate is 60-100 beats per minute. However, for people who are physically fit, it's generally lower. Also, resting heart rate usually rises with age.
