This allows the user to switch between oxygen-rich gas (~95% oxygen) to a lower concentration oxygen gas. This is similar to exercising at an altitude of 12,000 feet (~13% oxygen). By alternating between high and low oxygen concentrations, you’re able to simulate a high-altitude workout in short bursts (30 seconds).
This accomplishes two important benefits that standard EWOT will not. The first is that by switching to hypoxic (low-oxygen environment) levels, your circulatory and respiratory systems are forced to work harder, and this allows deep absorption and penetration throughout the body. The second important benefit is that by switching back to the high-oxygen reservoir, you will rapidly speed up the oxygen absorption rate and increase the solubility of oxygen into the blood.
