What is the suitable heart rate range for ordinary college students to exercise?

For a college student with an average health level, the reasonable load intensity during exercise should be between 65% and 85% of the maximum heart rate. The maximum heart rate refers to the limit heart rate during exercise, and the calculation method is: maximum heart rate (beats/minute) = 220- age. For example, when a classmate is 20 years old, his maximum heart rate should be 220-20 = 200 beats/min, and the best heart rate during exercise should be between 200 × 65% and 200 × 85%, that is, between 130 beats/min and 170 beats/min.
