what is an elevation training mask
The Elevation Training Mask is a breathing device that is similar to military gas masks (version 1 of Training Mask). Version 2 or 2.0 is simpler since it does not restrict eye vision (see the image on the right).
As a first step, it is necessary to understand why modern people have low body O2 content, are unfit, and suffer from diseases. Many people assume that the Elevation Training Mask is just another breathing device that is created to strengthen respiratory muscles and mimic effects of high altitude. However, it is not accidental that people claim more benefits after using the Training Mask in comparison with other resistive devices.
