ABSTRACT:
A breathing apparatus having a main body with a generally cylindrical inner cavity. The main body has a main aperture for the user to breath into and at least two sets of outer openings. An inner cylinder is coaxially disposed within the inner cavity of the main body and is adapted to move relative to the main body. The inner cylinder has an open end adjacent the main aperture, and at least two sets of inner openings selectively matable with the openings in the main body upon movement of the inner cylinder with respect to the main body. By selecting the appropriate alignment of openings, either resistive, percussive, or pulsing breathing exercises can be performed.
