Aerobic Exercises

Low-intensity, low-pulse rate endurance exercise, called aerobic. Aerobic means with oxygen. The aerobic energy system can be defined as burning fuel with oxygen. Your body burns stored fats and stored sugar in the presence of oxygen.

Aerobic exercises are very important. As your heart rate rises, the amount of oxygen in your blood improves, and endorphins, which act as natural painkillers, increase. Aerobic exercise activates your immune system, helps your heart pump blood more efficiently, and increases your stamina over time. But there is a cutoff point to these benefits, and if you push your cardio session too long it can actually harm your body in many harmful ways.
