Target Heart Rate Zone Calculator

How to calculate your Target Heart Rate?

The most widely used method for determining your Maximum Heart Rate (MHR) is the Fox formula. This calculation provides a helpful baseline to estimate the upper limit of what your cardiovascular system can safely handle during intense physical activity.

Formula: MHR = 220 - Age

Using the Heart Rate calculator: an example

Consider a 40-year-old user who wants to exercise specifically for fat burning. For this goal, fitness experts typically recommend staying within the 60% to 70% intensity zone of your maximum capacity.

Step-by-step calculation:

• Maximum Heart Rate (MHR): 220 - 40 = 180 bpm
• Fat Burning Zone (60-70%): 108 bpm to 126 bpm

Frequently Asked Questions

What is a normal resting heart rate?
Typically 60-100 bpm for most healthy adults.

How often should I check my heart rate during exercise?
Check periodically to ensure you are in the target zone and adjust your intensity accordingly.

Is the 220-age formula accurate for everyone?
It is a general estimate; athletes or individuals on specific medications may have different heart rate profiles.
