Low Intensity Cardio vs. High Intensity Cardio

By Span Johnson

People often question which is better for burning body fat, low or high intensity cardio exercise. The answer is, both will burn body fat, but which type of cardio exercise works better to burn those fat cells.

Your body stores excess complex carbohydrates as energy (referred to as glycogen) in the muscles and liver. This is what Scientists first believed that the body burns during high intensity cardio. While on the other hand they believed that the low intensity cardio would strictly burn fat cells.

The findings are not necessarily black and white though. Otherwise we would not have so many overweight people, even when they are doing the low impact exercises like walking and swimming that you see many are doing. It makes you wonder why it is not working for them.

Science has shown that low intensity cardio, when done in the proper amount is great for burning body fat; doing exercises like walking or swimming. But don?t discount the great effect that high intensity cardio has to offer. When exercising at a high intensity your body efficiently burns through the excess carbohydrates (glycogen) and looks for more sources of energy. It will search out body fat and burn that too.

As if that wasn?t great enough, when you continually make high intensity cardio a part of your workout routine, you can eat more complex carbohydrates without worrying about them being stored as fat. With a routine of cardio exercise of both high and low intensity your body becomes like a well oiled machine, efficiently burning fat and glycogen and converting new foods you eat into more energy (glycogen) for later burning. The more energy you burn, the more you replenish for future burning.

The best thing about high intensity cardio is that is has lingering effects on your body. It revs up your metabolism so much so that it continues to burn, after the glycogen stores are burnt up, it turns to the fat that is stored; even hours after your workout. You won?t find that residual effect with low intensity workouts.

You will not get the same lingering effect with low intensity cardio, even though it does burn the fat during your workout. It is the high intensity that really revs up your metabolism to burn calories.

Anyone can work their way into a combination of high and low intensity cardio workout routine. Try interval training that interjects spurts of high intensity exercise in with the low intensity ones. This is an awesome way to boost the fat burning going on within your body. Try intervals of walking/jogging/sprinting. But be careful to do this slowly and work your way up, to avoid injury or burnout.

One of the greatest benefits of exercise, especially cardio exercise is that it increases your energy. The more cardio you do, the more your body responds to it in a positive way; giving you energy to do more throughout your day. As mentioned above, you body becomes like a well oiled energy burning machine with consistency.

Please, don?t jump right into interval training or a high intensity workout if you are new to exercise. Ease into it to avoid injury and burning yourself out. Work your way up from low intensity to where you can work them both into your workout routine and benefit from the effects of a good balanced cardio workout.
