FAQ
What is target heart rate?
It is the heart-rate range that matches your training goal, such as fat-loss cardio, aerobic conditioning, or interval work.
What is the Karvonen method?
It combines resting heart rate with heart-rate reserve, which usually gives a more personalized range than simple max-HR percentages.
Do I need resting heart rate?
No. You can still get a standard estimate without it, but entering resting heart rate generally improves accuracy for your own condition.
Can this replace medical advice?
No. It is for workout planning only, not medical diagnosis. If you have symptoms or known heart conditions, follow clinical advice first.
