Endurance training indeed burns a lot of calories, but researchers believe it is not the most optimal way to get rid of your body fat.
When performing moderate exercise, your body burns fat but does so for energy. Performing in this manner most of the time sends the signal to your body to hold on to fat. Thus, with moderate exercise alone, your body will store more fat.
On the other hand, when you perform short bursts of more intense exercises, your body consumes a substance named glycogen that is stored away in the muscle tissues. This high intensity workout will condition your body to store more energy in your muscle rather than in your fat. Exercising like this is also more beneficial to burn fat throughout your rest period, as this is when glycogen is replenished in muscle restored.
