Many coaches of sport teams utilize aerobic training. Aerobics and also what is known as anaerobic training are central to an athlete's workout. They utilize what is called interval training which helps them to spend a significant amount of time in the aerobic range. The biggest beneficiary when doing aerobics is your circulatory system.
Those just starting out may feel a little intimidated by this especially if you area slightly out of shape. The key to the running intervals is to spike your heart rate quickly. When this has been achieved it will take a little while for your heart rate to come back down. The beauty here is this. Even during that comfortable cool down period your heart is still mostly in the aerobic range.
So what are aerobic activities? Walking and bicycling are considered aerobic activities even if you are walking slowly. What is the purpose of aerobic exercises? The central objective of aerobics is to burn calories from fat.
When you are doing aerobic exercises your body is working at a level which demands oxygen and fuel i.e. energy so its core benefit is burning calories and hence fat. The body needs fuel somewhere, I say give it all the fat. Long steady endurance aerobic training is not as advantageous when it comes to burning fat.
So rather than do aerobic exercises at constant speeds for longer periods of time opt to do the same time but increase intensity then cool down and then increase intensity again. The goal is to work out as hard as you are able to for short periods of time. This is known as interval training which will help you to burn off more fat.
