Formula:

The Fat Burning Zone is typically estimated as a percentage of your Maximum Heart Rate (MHR) and Heart Rate Reserve (HRR). We use the Karvonen Formula:
Target Heart Rate (THR) = ((MHR - RHR) × %Intensity) + RHR
Where:

  • MHR (Maximum Heart Rate) = 220 - Age
  • RHR (Resting Heart Rate) = Your heart rate at rest (beats per minute)
  • %Intensity = Percentage of your desired intensity (e.g., 60-70% for fat burning)
The calculator will provide a range for 60-70% intensity to optimize fat loss.
