Mask you a question?

Increasing the strength of your respiratory muscles (the ones that help you breathe: your diaphragm and the muscles between your ribs) will improve aerobic fitness, especially for long-duration tasks. Respiratory muscle training (RMT) can be achieved through whole-body aerobic exercise, upper-body strength conditioning, and some commercial RMT devices. However, using your military Pro Mask or other commercial mask device as a method of RMT is not going to prepare you for higher elevations. Studies have also found that RMT only slightly improves performance in those who are already aerobically fit, (i.e., military personnel); it has somewhat more benefit for those less fit or with chronic conditions. Your Pro Mask was made to protect your lungs, eyes, and face from chemical and biological agents, radioactive particles, and battlefield contaminants. It does not create enough airflow resistance to help improve aerobic capacity, and it wasn’t designed to be exercise equipment. In addition, there is no scientific evidence to show that using commercial masks at normal altitudes will improve your performance at high altitudes. You can read more from USARIEM about using Pro Masks and commercial products for exercise training, as well an overview of current information and recommendations.
