The lungs you are born with do not change like a muscle when exercised. For this reason, many people believe there isn't much that can be done to improve breathing for performance. I was fascinated to find out that while you can't change the lungs you have you can change how you use the lungs you have. In this episode of FASTER we welcome back Dr. Andrew Sellars and introduce Luke Way from Isocapnic. They've developed a respiratory muscle trainer that simulates your lungs at a increased effort. Normally, when rested, deep breathes will leave you lightheaded, but by intelligently regulating the CO2 that exits the body they are able to train your lungs while sitting on the couch. Listen to this episode to learn more about respiratory muscle training so you can become faster and increase your VO2 Max.
