Fat Burning Zone Calculator (Best Heart Rate to Burn Fat)

If you’ve ever ran on a treadmill and kept checking your heart rate in the so-called “fat burning zone” only to not see any change when you stepped on the weight scale?

You may be doing a lot of working out and cardio, but progress has frustratingly plateaued. As a personal trainer of 20 years, I hear this concern from new clients all the time. They think they’re staying in the “fat burning zone” but it’s something isn’t working.

Maybe you’ve been doing your cardio all wrong by wasting your time staying in the wrong heart rate zone. Slogging through slow and steady workouts can leave you frustrated without the results to show for it. You’re not lazy, you could just be in the wrong fat burning heart rate zone.

Below you’ll find an easy-to-use fat burning zone calculator. You’ll uncover your true fat burning zone when working out to lose weight.
