If you want to get rid of the fat, you don't have to melt in a sweat. The harder the body gets loaded, less fat it burns. The best way to determine your body's ideal load is to watch heartbeat.

Provide yourself with a heart rate meter. It will watch over your heart rate and reminds you when you are over your capability and also if your heartbeat is too low.

For approximate orientation:

If your pulse in a rest is 59 beats a minute:

* the highest pulse when exercising at the age of 20 to 39 is: 140
* the highest pulse when exercising at the age of 40 to 49 is: 135

If your pulse in a rest is 60 to 89 beats a minute:

* the highest pulse when exercising at the age of 20 to 39 is: 145
* the highest pulse when exercising at the age of 40 to 49 is: 140

If your pulse in a rest is 90 to 100 beats a minute:

* the highest pulse when exercising at the age of 20 to 39 is: 150
* the highest pulse when exercising at the age of 40 to 49 is: 145

And why is so important to exercise in aerobics range (it means that body has enough of oxygen)?

If the muscles get enough oxygen, than they burn fat. In higher intensity of exercise, body doesn't get enough oxygen, and than it burns reserve store of carbs and doesn't even mind about the fat.

Aerobic means "with oxygen", and refers to the use of oxygen in the body's metabolic or energy-generating process. Many types of exercise are aerobic, and by definition are performed at moderate levels of intensity for extended periods of time. To obtain the best results, an aerobic exercise session involves a warming up period, followed by at least 20 minutes of moderate to intense exercise involving large muscle groups while maintaining 60-80% of your maximum heart rate, and a cooling down period at the end.

So basically exercise takes you half an hour, you don't get tired and you don't have any cramps. Everyone should have that much time for this likable, easy and healthy exercise.

Think of aerobic activity as being long in duration yet low in intensity. Aerobic activities include: walking, biking, jogging, swimming, aerobic classes and cross-country skiing. Anaerobic activity is short in duration and high in intensity. Anaerobic activities include: racquetball, downhill skiing, weight lifting, sprinting, softball, soccer and football.

You should be able to carry on a short conversation while doing aerobic exercise. If you are gasping for air while talking, you are probably working anaerobically.

The goal when exercising aerobically is to hit your target heart rate and maintain it for the entire exercise session. This works the heart muscle more effectively and burns more calories. Less conditioned athletes will reach their target zones quickly because their heart muscle isn't used to the workload. As your heart becomes conditioned, you will have to work harder to reach the target zone.

So if you want to burn fat, don't rush - you'll get nothing but tiredness and hunger.
