Aerobic training such as walking or running on a stationary bike is a good way to accelerate the fat burning process, as long as it is not overdone and as long as it is used only in addition to a good weight
training program. It should never be used as a substitute for weight training since it does not permanently increase your metabolism and since it does not has the ability to re–shape your body. In order for aerobic exercise to be effective, it needs to be performed within the fat burning zone. The fat burning zone is the zone at which you are doing enough work to burn fat. Your pulse (how fast your heart is beating per minute) determines this zone.
-: The Fat Burning Zone :-
The fat burning zone formula is the following:
Fat burning zone=220–(Your Age) x (.75)
The result of your formula will give you an approximate value of how fast your heart should be beating per minute. For example, a 20–year–old would need to reach a pulse in the neighborhood of 150 beats per minute in order to be in the fat burning zone. It is important to remember that this is not an absolute figure, this is an approximation. So as long as you are plus or minus 10 beats from the number that the formula provides you with, then you can rest assured that you will be burning fat.
Another important point that needs to be raised is that in order for aerobic exercise to be an effective fat burner it needs to be performed at the appropriate times. There are only two times that aerobic exercise is effective in burning fat. The first time is first thing in the morning on an empty stomach after drinking 16 to 24oz of water in order to prevent dehydration. When performed at this time you burn 300% more body fat that at any other time in the day because your body does not has any glycogen (stored carbohydrates–sugar) in the system to burn. Therefore, it has to go directly into the fat stores in order to get the energy necessary to complete the activity. The other time where aerobic exercise is effective is immediately after the weight training session. The reason for this is that when exercise is not performed first thing in the morning it takes your body approximately anywhere between 20 to 30 minutes to start burning fat. This is because that it how long it takes the body to deplete its glycogen stores and switch to a fat burning environment.
Therefore, it would not be efficient to perform aerobic exercise by
itself at any other time during the day because you would need to perform it for 20–30 minutes just to get to the fat burning stage and for an additional 20 minutes just so that you burn fat. This would give a grand total of 50 minutes a day and in my opinion, I don’t
think that aerobic exercise should be performed for more than 45 minutes at a time since this would put you at a risk of losing muscle mass. Remember that more is not always better and this is especially true when it comes to aerobic exercise.
