Ever since we installed the MyZone training system, We’ve been getting a lot of questions!
One question we’ve heard a lot recently involves the “fat burning zone” chart featured on most treadmills and ellipticals.
Our members are wondering why we have them work at higher heart rates than the 60-70% recommended by the charts.
Let me clear this up: It’s absolutely true – the “fat burning zone” does exist. But it doesn’t tell you the whole story…
Your body does burn the majority of energy it uses from fat when you train at 60-70%.
But here’s where that information is misleading:
It’s all relative.
Let’s say that during a workout in the “fat burning zone”, you burn 100 calories. Now the majority of those calories will come from fat, so let’s just say 90% of them.
That means you burned 90 calories of fat! Pretty good, right?
Now, let’s take a look at what happens when you work at the zones we recommend:
When you work out at higher intensities (like our Fat Blast class), the majority of calories come from carbohydrate.
Here’s the kicker, though: you burn much more calories in high intensity work.
Let’s say 40% of the calories burned are from body fat. But that high intensity workout burned 400 calories.
That would mean you burned 160 fat calories for the workout.
That’s close to double!
And that doesn’t even count the excess calories your body burns for up to 48 hours after high intensity exercise.
Why do we work in high intensity ranges?
Because it burns more fat overall!
