Which method of calculating your target heart rate is more accurate?Group of answer choicesPercent of maximal heart rate (% max HR)Heart rate range (HRR)

The Heart Rate Reserve (HRR) method is generally considered more accurate than the Percent of Maximal Heart Rate (% max HR) method.

Here's why:

1. The % max HR method is based on the assumption that everyone's maximum heart rate is the same, which is calculated as 220 minus your age. However, this is a very general estimate and can vary greatly from person to person.

2. The HRR method, on the other hand, takes into account your resting heart rate (RHR), which is a more accurate reflection of your individual fitness level. The formula for HRR is: (Max HR - RHR) * %Intensity + RHR.

3. By including the RHR in the calculation, the HRR method provides a more personalized target heart rate, which can lead to more effective workouts.

So, while both methods can be used to calculate your target heart rate, the HRR method is generally considered more accurate.
