Cardiovascular training, or aerobic training, is a type of exercise that increases the endurance of skeletal muscles by making the distribution of oxygen by the heart more efficient. Cardio is a great way to lose weight and keep it off by burning lots of calories. Exercises of this type use large muscle groups, and involve raising the heart rate to a specific rate for at least 30 minutes.
Cardiovascular training is an important part of a health regimen. To optimize this type of training it should be performed at least three times a week, for a minimum of 30 minutes each time. Some popular cardiovascular training exercises are running, swimming, biking, spinning, and playing aerobic sports. Varying the cardiovascular activity, a practice called cross-training, can be even more effective than using just one.
