By now you know that aerobic exercise burns fat, but doing to much aerobice activity breaks down amino acids and that those amion acids are coming from muscle tissue, which can cause the loss of muscle!
There is another term we need to become familiar with and that is anaerobic exercise. Anaerobic means without oxygen. Aerobic you might have guessed means with oxygen. Anaerobic exercise are activityes in which you become exhausted very quickly (ie sprinting or weight training). Anaerobic activities build muscle. What you should know anerobic exercise develops muscle and aerobic exercise burns fat. Fat is burned inside the muscles. As you develop more muscle you have the ability to burn more fat when you do the appropriate amount of cardio (aerobic) activity. Good news right? Well for most yes, but for others the image of getting big muscular body is not something they want to visualize. Let us examine the commonly used phrase, “I don’t want to get big I just want to get toned.” Take a deep breath, “toned” means to grow or gain muscle. What happens here is as the muscles grow they utilized more fat in the body. As the muscles demand the use of fat stored in the body the muscles grow the fat disappears and you begin to see muscle definition- muscle tone!
So how do you build muscle? In order to build muscle you must ask the muscles to do more work than they are accustomed. Then provide supportive nutrition to supply the muscles with the right nutritients to grow.
To sum it up. Aerobic exercise builds muscle. Fat is burned inside muscles. Aerobic exercise is the primary system in which to burn fat. More muscle means faster utilization of fat.
