Claim:
1. A resistance breathing device, comprising: a face mask having an interior surface, an exterior surface opposite said interior surface, an aperture extending through said face mask from said exterior surface to said interior surface, and a perimeter, wherein said face mask is adapted to overlay a user's mouth and nose such that said perimeter forms an air-tight seal with the user's face and around the user's mouth and nose and said face mask defines an internal area between said interior surface of said face mask and the user's face; an outer layer overlaying said face mask and having a pair of straps with inter-engaging ends for affixing said face mask about the user's face; an insert having an interior surface, an exterior surface opposite said interior surface of said insert, and at least one inlet aperture extending therethrough, said insert being positioned within said aperture of said face mask; an adjustment slide including an interior surface, an exterior surface opposite said interior surface of said adjustment slide, and at least one inlet aperture extending therethrough, said adjustment slide being positioned adjacent to said insert such that said interior surface of said adjustment slide abuts said exterior surface of said insert, said adjustment slide being movable linearly along a linear axis with respect to said insert between a first position and a second position, wherein when said adjustment slide is in its said first position, a first portion of said at least one inlet aperture of said adjustment slide overlays a first portion of said at least one inlet aperture of said insert, and wherein when said adjustment slide is in its said second position, a second portion of said at least one inlet aperture of said adjustment slide overlays a second portion of said at least one inlet aperture of said insert, said second portion of said at least one inlet aperture of said adjustment slide being larger in size than said first portion of said at least one inlet aperture of said adjustment slide; an adjustment wheel attached movably to said insert such that said adjustment wheel is movable rotatably with respect to said insert between a first position and a second position, said first position of said adjustment wheel corresponding to said first position of said adjustment slide, said second position of said adjustment wheel corresponding to said second position of said adjustment slide, whereby when said adjustment wheel is moved between its said first position and its said second position, said adjustment slide is moved between its said first position and its said second position; and an air exhaust valve assembly adapted to prevent air from passing therethrough from an external environment to said internal area of said face mask, said air exhaust valve assembly being adapted to allow air to pass therethrough from said internal area of said face mask to the external environment.
