Interval Training for Maximum Fat Burning

What IS the best way to train for maximum calorie burn?

For many years, the traditional thinking has been keeping the heart rate in a certain zone, called the "fat burning zone." Sounds good, but it's dead wrong. Research shows that interval training at intensity greater than 90% of the VO2 max (maximum oxygen consumption during exercise), is the best way to improve cardio fitness and significantly aids in post-workout fat burning. A recent study showed that women who did high-intensity interval training seven times over two weeks increased whole body fat usage during exercise by 36%. They also increased fat burning enzyme activity and increased VO2 max by 13%. So, if you want to burn that belly fat, high intensity interval training is the key.
