Wikipedia does an excellent job of describing the Karnoven Method:
Target Heart Rate = ((Maximum Heart Rate – Resting Heart Rate) × %Intensity) + Resting Heart Rate
So, for someone with a Maximum Heart Rate of 180 and a Resting Heart Rate of 70 we have two examples:
For A 50% Target Heart Rate: ((180 - 70) × 0.50) + 70 = 125 bpm
For a 85% Target Heart Rate: ((180 - 70) × 0.85) + 70 = 163 bpm
