Get Fit Exercises

The American College of Sports medicine on aerobic exercises

When you exercise really hard, you breathe more heavily. This starts the aerobic process within your body and your immediate available energy source (which usually starts with the sugar based store of energy called glycogen), is converted to energy for that muscle activity.

If you continue to exercise hard in the same session, you will (eventually) use up that immediately available glycogen energy source. If you continue to exercise even beyond this in the same aerobic exercises session (assuming you're not too tired to continue), then your body will need to find another source of energy - this is when your amazing body will convert fat, stored in your body, into energy. Long distance marathon runners typically experience this around the 17 mile mark and it is often referred to as "hitting the wall". It is the moment when your body has run out of gylcogen energy levels and has not yet converted the fatty acid based energy store. The good news is that you can train your body to prepare for this moment - but it's still a dodgy time for novice runners.

I know that the above is a very simplified summary of the actual process caused by aerobic exercises that is going on in your body, but you should get the picture.

So, if you start your aerobic exercises regime with only moderate levels of sugar (glycogen) based energy in your body, then you will reach the fat burning level more quickly. So the less sugary based foods, the faster the fat burn.

The other good news is that your body can be trained to start burning up fat even before your sugar based (glycogen) levels are depleted. This won't happen immediately and you will need to keep at your aerobic exercises for weeks before things start to change.

Broadly speaking, aerobic exercises can help more with weight loss - anaerobic exercises help less (they tend to build muscle).

Examples of aerobic exercises are:

Aerobic classes that can be dancing to music or step dancing (fast movements).
Treadmills
Exercise bicycles
Ski machines
Air gliders
Jogging and running
Sports such as racquetball and handball
