The target heart rate zone is the range of exercise intensity that allows you to stress your cardiorespiratory system for optimal benefit without overloading the system.
The target heart rate of an individual refers to the heartbeat range during exercise and is measured as a percentage. The resting heart rate is calculated by checking the pulse beat for one minute. It normally ranges between 60-100 beats/minute. The target heart rate is 220 subtracted by the age of an individual. For example, the target heart rate for a 27-year-old would be 220-27= 193 beats/minute. Therefore, at a 50% exertion level, the target heart rate must be 50% of the maximum value, that is, 97 beats/minute.
