How is the Target HR calculated using age?

The formula for calculating Target Heart Rate (HR) based on age is widely recognized as Target HR = 220 - age. This method provides a straightforward way to estimate a person's maximum heart rate by subtracting their age from 220. The result then can be used to establish a desired training intensity, often expressed as a percentage of the maximum heart rate.

For example, if someone is 30 years old, their estimated maximum heart rate would be 220 - 30 = 190 beats per minute. This number serves as a reference for determining various training zones, such as moderate or vigorous intensity.

Understanding this formula is vital for fitness instructors as it helps clients tailor their exercise programs to improve cardiovascular fitness safely and effectively, ensuring they are working within an appropriate and safe heart rate zone based on their age.
