Explain why a good exercise program should include both aerobic and resistance training?

Aerobic exercise is an important form of exercise that utilizes the use of the heart and lungs. It is a low intensity exercise, so it can be performed for prolonged periods of time without exhaustion or risk of injury, which is especially good for older individuals. It also can be used for fat loss. On the other hand, anaerobic exercise has more benefits for those who are capable of high intensity exercise and for those with interests in increasing cardiovascular health and athletic abilities. Anaerobic exercise stresses both the cardiovascular system and muscular system. Benefits include: a decrease in body fat, an increase in cardiovascular function, speed, power, and agility. Yet, anaerobic exercise such as high intensity interval exercise should not be over performed because it stresses the body, which could lead to overtraining and injury. Anaerobic and aerobic exercise should be used in moderation.
