Cardio exercise is any exercise that raises your heart rate. To keep  muscles in shape we need move them. This movement makes them stronger and stronger muscles make for a more efficient and healthy body. The heart is a muscle and working it makes it stronger. A stronger cardio-vascular system means more capillaries delivering more oxygen to cells in the  muscles. This enables cells to burn more fat during both exercise and inactivity.

Cardio exercise uses large muscle movement over a sustained period of time keeping the heart rate to at least 50% of its maximum level. Sample cardio workouts would be walking, running, bike riding, and swimming, rowing and aerobic workouts.

Workouts should cause moderate sweating. If you can’t finish a sentence while doing your workout you are going at it too hard. If you are having no trouble talking step it up. You need a minimum of 20 minutes of continued elevated pulse to get the best results at least 3 times a week. Cardio exercises will burn fat. Weight loss comes from burning more calories than you take in. Even when you see no specific weight loss you are getting great benefits from a cardio workout.
