A pulmonary muscle trainer consisting of a tubular body having a poppet valve dividing the body into two sections. The poppet is adjustably biased into the closed position, whereby inspiration of a given intensity will be sufficient to overcome the bias and allow air flow through the unit. The poppet is supplied with a one-way valve element to permit the user to create an unrestricted expiration air flow to allow a breathing rhythm to be established. In a preferred embodiment bias is maintained on the poppet by a spring whose compression is adjustable by means of a collar manually positionable within the body of the unit. By the use of the poppet a constant threshold pressure load may be applied.

A lung/diaphragm exerciser device comprising a tubular body defining a chamber having open first and second opposed ends therein, movable sealing means mounted within said chamber for movement between a first position restricting the passage of air from said second end to said first end and a second position whereby said restriction is removed; bias means mounted within said chamber to resist motion of said sealing means from said first position to said second position, and valve means mounted within said chamber allowing the free passage of air from said first end to said second end while prohibiting the passage of air from said second end to said first end.
