Frequently Asked Questions
What is target heart rate?
Target heart rate is the ideal range for exercise intensity. The simple formula: MHR = 220 - age. For fat burning, aim for 60-70% of MHR. For cardio fitness, 70-80%. The Karvonen method is more accurate and uses resting heart rate: THR = (MHR - RHR) × %intensity + RHR.
