Target Heart Rate Calculator
Calculate your target heart rate zones for fat burn, aerobic, and peak training intensities using the Karvonen method.
Input Parameters
Enter details for calculation.
Target Heart Rate
Expert Tip
Training within specific zones optimizes target physiological adaptations (e.g. fat oxidation vs cardiac capacity).
Calculation Methodology & Details
Formula
Uses the Karvonen formula, which accounts for resting heart rate to establish relative cardiovascular intensity.
