Cardio is a form of exercise that results in an increased heart rate as well as improved muscular functioning which ultimately leads to general body fitness. Cardio as a form of physical exercise, involves engagement of larger body muscles, often referred to as gross motor activities. Apart from raising the heart rate during exercise, cardio exercise also enables our muscles to maintain a good shape and condition. This results in a more healthy and efficient functioning body, while helping us to achieve the primary goal of cardio exercise, which is a stronger cardio vascular system that is characterized with more capillaries carrying more oxygen to the muscular cells. Increased oxygen supply in turn allows your body to break down more fat during exercise as well as during resting period.
Low intensity exercise rates for an elongated period of time enables you to participate in the cardio form of exercise. For instance, engaging your body in rhythmic exercises for more than 15 minutes while maintaining 60 to 80% of your maximum heart rate is an ideal way of taking part in cardio exercise. This leads to a number of health and fitness benefits such as increased stamina, control of body weight and other benefits related to psychological and mental functioning of the body including reduced anxiety and enhanced moods.
