What causes me to run out of breath at the end of a race?

This occurs when your muscles, including the muscles surrounding your lungs, are tired and fatigued. Training with PowerLung can strengthen your lung muscles. Trained lung muscles have a higher endurance level and can result in better performance and race time.
