The secret of truly elite athletes isn’t the amount of time spent working out, the intensity of the workout, or the determination to push one’s body to its limits. The secret is the power of respiratory muscle conditioning. Until the Training Mask there was not an effective way to improve pulmonary performance beyond running harder or doing more work sets. Yet even with increased work volume, one may not improve their stamina or endurance beyond a fixed point. This is why top level athletes and strength coaches from prestigious organizations such as the NFL, NBA, and MLB have started incorporating the Training Mask into their programs.
