Exercises that are both high and low intensity exercise can enable your body to burn fat. But, have you ever wondered which type of cardio exercise is better for your health? Sometimes burning more body fat is not a good option for your health and there are many side effects. However, in most cases burning fat quickly can help a person to overcome some major ailments. When you exercise extensively your body tends to burn glycogen. This glycogen comes from carbohydrates that were previously stored in the muscles and liver. On the other end, low intensity exercise does not cause the body to burn extensive fat. High intensity cardio exercises can increase your metabolism long after your workout is completed and as a result the fat burning process extends to many hours after you are finished exercising. This does not happen with low intensity exercises. Cardio is known for its ability to help you become more energized if you do it more frequently and it can also help you in burning your calories.
