Target Heart Rate

Target heart rate zones help athletes train at the right intensity for different fitness goals. Fat burning, aerobic base, and high-intensity intervals each require different heart rate ranges, calculated as a percentage of maximum heart rate (MHR)

The calculator uses the standard published formula for target heart rate. Results are accurate to the precision of the inputs you provide. For financial, medical, or legal decisions, always verify with a qualified professional.

This calculator works with inches, percentages. You can enter values in the units shown — the calculator handles all conversions internally.

The calculator applies the standard formula for this type of calculation. See the 'How It Works' steps above for the detailed formula breakdown.
