Is afterburn real?

You’ve probably heard that High Intensity Interval Training (HIIT) produces an “afterburn effect”, which means your body continues to burn extra calories at an elevated rate for 24 hours after the completion of your workout.

Sure that’s sounds amazing, but is it too good to be true?

The Science of “Afterburn”

There is a scientific term for afterburn: excess post-exercise oxygen consumption (EPEOC). This refers to the oxygen that your body needs to restore after a heart-pounding workout.

So afterburn is indeed real.

While you exercise your body needs fuel to keep your muscles firing, and this requires oxygen to transport the fuel into the muscles. This causes your metabolism to rev up to an elevated state during and after exercise.

Intense Exercise = Intense Afterburn

Studies show that there is a direct correlation between the intensity (dictated by amount and frequency of muscle recruitment) of your workout and the amount of calories burned during the afterburn period.

BUT….. HIIT isn’t the only way of getting this afterburn effect. This can be accomplished with a simple, but well structure strength training program as well.

Intense and vigorous exercise keeps your body burning calories hours after the workout is through. And this is not the only benefit to workouts that recruit a lot of muscle – there’s also the bonus of increased muscle tone, fat loss and an increase in your aerobic capacity.

Keep this in mind the next time that you push yourself through a workout. Remember that intensity pays off, plus Strength Training and HIIT workouts have more proven benefits than a steady state cardio workout.
