There are many ways to improve one’s respiratory system. Exercise has always been one of the best ways to do so. Basically, there are only two main types of exercises: isometric and aerobic.

Aerobic exercises are usually endurance types of exercises, such as jogging or using a treadmill. When doing strenuous exercises like these, your use of oxygen transforms substances in your body such as glucose and amino acids into energy. This happens often during both running and walking.

Isometric exercises are more commonly know as resistance type exercises. Examples of this type are weight lifting and any exercises that will cause an increase in muscle strength. Isometrics makes your muscles contract. It makes bones stronger, increases one’s tone, helps to prevent injuries and you end up with stronger muscles, including the lungs and heart.

One must remember that the heart is a muscle. When you exercise, you are taking in oxygen and removing carbon dioxide from your body at a more rapid rate. With exercise, you increase the size of the heart muscle and make it more efficient. This will aid the lungs in providing more oxygen to all of the body.

Exercise involving isometrics involves the static contraction of a muscle without being able to see any movement in the joint's angle. Therefore, during isometric exercises, the length of the muscle doesn’t change. Through resistance exercises, a persons muscles are used in opposition with other muscles in order to increase strength. It is especially used for maintaining good physical fitness, strength training and for bodybuilding. All of these lead to a stronger heart and thereby strengthening the lungs and increasing the way they can do their job.
