It all starts with breathing. The average healthy adult inhales and exhales about 7 to 8 liters of air per minute. Once you fill your lungs, the oxygen in the air (air contains approximately 20% oxygen) is filtered through small branches of tubes (called bronchioles) until it reaches the alveoli. The alveoli are microscopic sacs where oxygen diffuses (enters) into the blood. From there, it’s a beeline direct to the heart.

What are the Health benefits of Aerobic Training?
- Aerobic exercise (“cardio”) makes the body more efficient at delivering oxygen to the rest of the body, helping heart health, lung function, and more.

- Your heart pumping and oxygenated blood flowing, with the goal of improving your cardiorespiratory health. But it benefits more than just your heart.

- That means aerobic exercise makes the heart more efficient and capable of moving more oxygen-carrying blood with every beat. The lungs adapt to be able to take in more oxygen, and the muscles become equipped to use more oxygen.
