In The Oxygen Advantage book you will discover the fundamental relationship between oxygen and the body. Improving fitness depends on enhancing the release of oxygen to your muscles, organs, and tissues. Increased oxygenation is not only healthier it also enables greater exercise intensity with reduced breathlessness. In short, you will be able to discover better health and fitness as well as better performance. If you do compete, you’ll also enjoy your training and competition more than ever, because you’ll be able to achieve more with less effort. Overall fitness and sports performance is usually limited by the lungs – not by the legs, not by the arms, and not even by the mind. As anyone who engages regularly in exercise knows, the feeling of intense breathlessness during sporting activity dictates exercise intensity far more than muscle fatigue. The foundation of enjoying and improving physical exercise therefore is to ensure that breathing is optimal and efficient. Increase VO2 Max: • Improve VO2 Max & Running Economy The Oxy...
