Everyone has wondered at some point in time which
cardio exercise is better.  To put it in simple
terms, both low and high intensity exercises will
help you to burn off body fat.  The question here
is which is the most effective to burn off more
body fat. 

When scientists first discovered that during
intensive exercises, your body burns glycogen, which
is a form of stored carbohydrates that are stored
in your liver and muscles for energy.  During low
intensity exercises, your body will burn a lot of
fat.

If your wondering whether or not it works, the
answer is no because there are so many obese people
still around.  Even though they are working out
with low intensity routines, it still makes you
wonder how it can be.

The scientists were right when they said the human
body burns more body fat during low intensity
exercises like walking or swimming.  During a
high intensity exercise such as running, the body
will burn a lot more calories.  Even if some of
the calories burnt are from glycogen, there are
still many fat calories burned as well.
