Okay, that makes some sense if I understand correctly.. Basically, the psoas diaphragm naturally lifts from the deep inhale. Seems the main difference then would be the intentional clenching, though that can require less force when using the natural lift created by the low and deep inhale. I can see how the belly naturally sinks back before the exhale when doing it this way too. That helps. Thanks!
The psoas-diaphragm connection descends on inhale in both methods of breath; it is the other structures that are different. The "general motion" of the diaphragm is
roughly similar between natural & reverse breathing.
Those are the actual physical movements of the diaphragm, not by someone's experience. When the abdomen was indented, the diaphragm moves upward, the compression will take place against the lungs.
PS....
Where is the insulting coming from. I don't understand.... 
I would puke if I tried breathing like that, CD. I dont know where you are getting that from, but
imho, it is absolutely erroneous. And I am going by the physical motions of my diaphragm, not somebody's theoretical understanding of how they think it should be. If you are raising your diaphragm on inhale, "ur doin it wrong." The dantien compresses, not the lungs.
Even in mildly complex systems, any outcome is the wrong thing to target, with the process being where the focus should be.
