Collection of Diaphragm Control Exercises

We all want to improve our breathing, both on and off the horn.  After seeing a vocal coach on television tell a singer to "expand your diaphragm out", I decided to do some research.  I have scoured the internet and believe that I have compiled an exhaustive list of every available exercise that will help with controlling the diaphragm.

Here is the complete list of exercises I found:
