Your maximum heart rate (HRmax) is the highest number of beats your heart can handle during intense physical activity.

Your maximum heart rate (HRmax) is the highest number of beats your heart can handle during intense physical activity. Your personal max heart rate is useful to know in order to determine your ideal cardio training zones. A lot of athletes calculate their max heart rate to estimate their Zone 2 training range. You can calculate that here: Zone 2 Heart Rate Calculator.

There are 5 different methods of measuring your max heart rate. Each method has pros and cons:

Method 1: 220 − Age — Easiest and most common
Method 2: Tanaka Formula — More accurate for adults over 40
Method 3: Gulati Formula (for WOMEN) — Designed specifically for females 👩‍🦰
Method 4: Field Test — Most accurate outside a lab (but demanding)
Method 5: Lab Test — Most scientific and precise, but requires a clinic

Method 1: 220 − Age

This is the most common and simplest method. You just subtract your age from 220 to estimate your maximum heart rate.

Enter your age:

Method 2: Tanaka Formula

A more accurate formula for adults, especially over 40. It calculates your HRmax using:
208 − (0.7 × Age)

Enter your age:

Method 3: Gulati Formula (for WOMEN) 👩‍🦰

Designed specifically for women. This formula estimates HRmax with:
206 − (0.88 × Age)

Enter your age:

Method 4: Field Test Method

This is the most accurate non-lab method. Perform a 20–30 minute all-out run or bike effort. Your highest sustained heart rate toward the end is your HRmax. This method requires a heart rate monitor and strong effort.

Method 5: Lab Test*

*This is the most scientific and precise method. It requires a lab test using equipment like a VO2 max or blood lactate test. These results provide the most accurate max heart rate reading, but may not be easily accessible.
