Heart Rate Training Zones

Karvonen Heart Rate Training Zones

Karvonen uses both your maximum and resting heart rates to calculate your zones. It subtracts your resting heart rate from your maximum to give a heart rate reserve. It then calculated your percentage using your heart rate reserve then adds the resting heart rate back on to give the final figure. The idea is you adjust your zones from day to day based on the resting heart rate figure you take each morning.
