What is a good heart rate zone for fat burning?
Zone 2, roughly 60 to 70 percent, is the steady aerobic range often used for fat burning and endurance.
From the tool guide Ask a follow-upWhich formula is most accurate?
Tanaka and Karvonen are generally considered better than 220 minus age, but all are estimates.
From the tool guide Ask a follow-upDo medications change my zones?
Some, such as beta blockers, lower heart rate. Ask your doctor before using these zones.
From the tool guide Ask a follow-upWhat this tool does
Training at the right intensity is the difference between building endurance, burning fat and simply exhausting yourself. Heart rate zones split effort into five bands, from very light recovery to all-out effort. Enter your age, add your resting heart rate for the most personal result, and pick a method: Karvonen (heart rate reserve), Tanaka (208 minus 0.7 times age) or the classic 220 minus age.
How to use it, step by step
- Enter your age.
- Enter your resting heart rate (or leave the default).
- Choose a method.
- Read your max heart rate and zone table.
Tips from the guide
- Measure resting heart rate on waking, before getting out of bed.
- Most training time should sit in Zones 2 and 3.
- A real max heart rate test is the only precise method. Formulas are estimates.
Common mistakes to avoid
- Treating the formula as exact. Individual max heart rate varies by around 10 bpm.
- Ignoring how you feel. Effort and breathing matter as much as numbers.
- Training hard every day with no easy days.
Who uses it
- Runners and cyclists. Pace easy days properly with Zone 2.
- People losing weight. Stay in a sustainable fat-burning range.
- Anyone using a fitness watch. Cross-check the zones your device gives you.
How to ask a question people can answer
A good thread on the Heart Rate Zones Calculator saves everyone time. Start with a title that names the exact problem, such as the input you used, the result you expected and the result you got. A title like “Not working” is hard to answer, while a title with the specifics gets replies quickly.
- Say what you tried. List the steps you followed and any settings you changed, so replies do not repeat what you already did.
- Share a small example. A short sample input and the output you saw is worth more than a long description. Remove anything private first.
- Mention your setup. Your device, browser and whether you are on a phone or a computer can explain many odd results.
- One question per thread. Separate topics get clearer answers and are easier to find later with the search box above.
- Come back and reply. If a suggestion worked, say so and upvote it, and if you found the fix yourself, post it for the next person.
