Aerobic Exercise

Aerobic exercise:

It is very important and it is very much necessary to be fit and fine.Aerobic exercise can be any type of exercise that causes your heart rate to increase and makes you breath harder than normal.But don’t worry, you don't have to join any “aerobic” classes to benefit from aerobic exercise. Aerobic exercise is a very useful tool in fat burning too.

The body has two sources of energy :

sugar and fat.Sugar or glycogen is stored in the liver and muscle and is the easiest from of energy for your body to use. Glycogen is the bodies preferred source of energy. Fat on the other hand, requires more work to be used as energy.
Why? The problem is that fat can be broken down only as long as oxygen is available. Oxygen must be present for your body to burn fat for energy, but not to burn glycogen. In the initial stages of exercise, oxygen is not available.
It can take minimum of 20 to 35 minutes of constant exercise before fat is fully available to the muscles as fuel. How efficiently your body burns fat will depend on your current condition.Exercise, particularly aerobics, enhances the development of capillaries to the muscle which in turn improves the blood flow wherever it’s needed. With better blood flow and improved oxygen uptake by the muscles, your body becomes better adapted at building muscle.
This is the most leading reason why you shouldn't neglect the aerobic part of your training.
