Anaerobic Threshold Calculator

Calculate Your Anaerobic Threshold Heart Rate

Enter your known MHR, or estimate (e.g., 220 - your age).

Your Estimated Anaerobic Threshold

Based on your inputs, your estimated Anaerobic Threshold (AT) is:

BPM

This is an estimation. Individual physiological variations may occur.

Unlock your athletic potential with our Anaerobic Threshold Calculator. Easily estimate your AT heart rate to define precise training zones, maximize endurance, and prevent overtraining. Essential for runners, cyclists, and all endurance athletes aiming for peak performance.

Formula:

The Anaerobic Threshold (AT) is often estimated as a percentage of your Maximum Heart Rate (MHR), varying based on your training level.

Formula: AT (BPM) = MHR × Percentage (%)

Where:

  • MHR = Maximum Heart Rate (beats per minute)
  • Percentage (%) = A factor based on your training level (e.g., 0.80 to 0.92)
