Title: Heart rate
Passage: For healthy people, the Target Heart Rate or Training Heart Rate (THR) is a desired range of heart rate reached during aerobic exercise which enables one's heart and lungs to receive the most benefit from a workout. This theoretical range varies based mostly on age; however, a person's physical condition, sex, and previous training also are used in the calculation. Below are two ways to calculate one's THR. In each of these methods, there is an element called ``intensity'' which is expressed as a percentage. The THR can be calculated as a range of 65--85% intensity. However, it is crucial to derive an accurate HR to ensure these calculations are meaningful.
Question: the target hr zone is the range between 60 - 80 of an individual's maximum hr
Answer: no
