Frequently asked questions
How do I calculate my maximum heart rate?
Max HR = 220 - age. A 35-year-old has a max HR of about 185 bpm. The target heart rate calculator shows zones for fat burn, cardio and peak training.
How do I use the Karvonen method for heart rate zones?
Karvonen uses heart rate reserve: target HR = ((max HR - resting HR) x intensity%) + resting HR. The heart rate zones calculator does this for accurate training zones.
How many calories does heart-rate-based cardio burn?
Calories = MET x weight (kg) x time (hours). The calories burned calculator estimates calories from heart rate during cardio sessions.
