Cardio training is continually moving your large muscles like the legs to increase heart rate and burn sugar and eventually fat as an energy source to keep you moving. 
Cardio training is important for a healthy heart and weight loss. A good 30-60 minutes of cardio training is  good each day.
Always be aware of how you feel when you exercise. If you feel dizzy or light-headed, stop immediately and rest or call your doctor. If you're not breaking a sweat, speed it up!  
When doing cardio training, you should stay within your target heart rate zone. Most people should be exercising in a zone that is 60 to 80% of their predicted maximum heart rate. Take your pulse at your wrist while you are exercising for 10 seconds and multiply by 6. Apply the result using the Karvonen formula. This formula assumes that at birth a newborn’s heart is capable of a maximum heart rate of 220 beats per minute and with each year the maximum heart rate decreases by one beat per minute as you age. It has an accuracy rate of + or - 10-12 beats per minute and may not be as accurate for those over 65 who may have significantly higher heart rates.
