Final answer:
When determining estimated max heart rate, you subtract 220 from the age of the individual.
Step-by-step explanation:
The number you subtract from the age when determining estimated max heart rate is 220. The formula commonly used is 220 minus the age of the individual. For example, if a person is 30 years old, their estimated max heart rate would be 220 - 30 = 190 beats per minute.
