Aerobic exercise - Heart And Health Benefits

Aerobic exercise has a lot of heart and and other health benefits. Aerobic activity offers a wide variety of benefits to overall fitness and health. The visual improvements are great, but the long term, more important advantages occur on the inside. Together with cardiovascular efficiency, metabolic changes will take you another step closer to achieving ultimate fitness. You know aerobic exercise causes your body to burn calories, a percentage of which come from fat, depending upon (among other things) duration and intensity. But did you know that you continue to burn fat even after your workout is over? After training, the body needs to replenish muscle glycogen, and fatty acids help to manufacture adenosine tri phosphate(ATP). Basically, fat is used to partially refuel the body for its next burst of energy. The more intense the exercise, the more the body has to replenish, and the more fat it will use to do just that. Now as far your heart goes, aerobic exercise lowers your resting heart rate, increases stroke volume and improves the efficiency of the heart. A trained heart doesn't have to work as hard to deliver blood to the various parts of the body and can pump more blood with each beat than an untrained one. Aerobic training can also lower blood pressure, which in turn decreases the risk of heart attack.
It is recommend that your aerobics sessions should be at least 15 to 20 minutes in length. Although beginners should take it easy when first starting aerobic training. Beginners should start off doing 5 to 10 minutes of aerobic training and try to gradually increase the amount of time at every new workout when it feels comfortable to do so.
