Lungs represent the body’s physical conditioning. Once the lungs are functioning at peak performance, innately the rest of the body is conditioned. Responsible for processing air, lungs remove the oxygen to transfer it to the blood stream for distribution throughout the body. The volume of air the lungs may process is the initial restricting factor that demonstrates each individual's physical condition.

Have you ever wondered why most exercises or fitness instructors focus on your breathing? It is due in part to proper breathing. When intakes of air are appropriately administered during exercise, it offers a maximum load of oxygen needed for physical endurance.

When to inhale and exhale is another commonly posed question regarding exercise. In Pilates and yoga classes, instructors instruct participants to inhale on the shortening of the muscle (contraction). During the lengthening of the muscle (expansion) physical trainers recommend exhalation. Generally, most personal trainers recommend the bi-polar opposite breathing pattern: on the inhalation contraction of the muscle and on the expansion, exhalation.

It’s not recommended to hold one’s breath during a weight or resistance training. It may result in higher blood pressure. With an elevated blood pressure, it is more challenging for the heart to pump blood. Inevitably, it will reduce the blood flow to the brain.

In certain cases, individuals may find themselves expanding breath while exercising because of the elevated heart rate. As a result, oxygen will need to travel to the muscles at a rapid rate. Quite common during an aerobic or cardiovascular workout (i.e.: bike riding, jogging and roller blading). During weight training, the heart rate will innately elevate in confluence with breathing patterns to promote the flow of blood to the muscles.
