I am just not finding a tutorial for this, and python scripts arent helping. Also, I don't need the facial expressions, just the breathing animation.  

Try mouth-to-mouth resuscitation!

Or alternate the inhale morph between +1 and -1.

Using the Parameter Dials, go to Deformers,  Morphs|Shapes, Morphs++, Upper Torso.
Then enter 1.000 on Inhale ,  step forward a few frames, enter -1.000, step forward a few frames,
enter 1.000, etc.  That's what I do anyway.

there is an 'inhale'  morph  in  the 'upper torso'  section of the Morphs ++ set

There is??? Gee I never really pay much attention to the upper torso except when I am trying to bend them backward... :laugh:

There should be a coordination of the inhale function which will thrust out the chest and the abdomen moving out as the diaphragm lowers on a drawn breath.

Sometimes you can fake the effect by xRotation the abdomen one direction and the chest the opposite direction.  Bending them into each other by equal and opposite amounts make's it look like the figure is breathing.
