Breathing higher levels of oxygen during exercise increases strength, endurance, and stamina. You can go longer with greater power. This means a more effective workout in the same time frame. In addition, the body operates better when your blood is oxygen rich. Top athletes will travel to the lowest elevation to breathe higher purity of oxygen while training. However, this purity is only 2-5% more than the standard 21% you breathe on average. EWOT will increase your purity by at least 40% (or 10x more than the lowest elevation).
For those unable to use the Hyperbaric Chamber this is a great alternative for getting the benefits of increased oxygen. You will be on a stationary bike or concept 2 rower to bring your heart rate up over 110 BPM. While your heart rate is up your breathing in 95% oxy gen through a special mask designed for more athletic use. Raising the HR creates a delivery system for the oxygen for maximum absorption.
