Cardio Workout

 is good for your heart. Your heart is a muscle, and like all muscles, benefits and improves through exercise and training. Cardio workouts benefit your whole cardiovascular system. Plus, cardio workouts burn calories.
In a cardio workout, your activity level increases your heart rate. A cardio workout is aerobic when it also increases your breathing and oxygen intake. If you’re new to cardio workouts, let your body be your guide to the right cardio workout level for you. If ever you feel lightheaded or dizzy, stop and rest. If you’re not breaking a sweat, you’re not working hard enough, so pick up the pace.
