Using The Training Mask in addition to your conditioning workout can greatly improve overall fitness and reduce the time it takes you to complete a workout. Elevation masks make your respiratory muscles stronger and more efficient, meaning unparalleled workout stamina, endurance and recovery.
An altitude training mask emulates training at high altitudes which is a tactic used by many high performance sport athletes in cardio training. By reducing oxygen during a workout your cardiovascular system needs to work harder and adapt to storing energy. When you unmask, your body uses oxygen more efficiently increasing performance in competition.
