[Wronski Feint]

one of my favorites is "as i walk through the valley by the shaddow of death, i will fear no evil because i am the baddest motha***** here."   It works really good when youre scared.

take a deep breath and hold.

then release it vocally starting as high pitched as you can and SLOWLY! going to as low a pitch as you can..

think about a comical scream of someone falling of a cliff..

the internal resonance should start in your head and travel down through your body to your sacrum.

you can do it with your mouth open and closed to vibrate and exercise the different muscles.

another is just keep chanting "la la la la"  as fast/slow  high/low pitched as you like.

at the end of the day its all about penetrating your innards with the vibrations created by your voice and doesnt really have anything to do with the meaning of the words you use (unless its some kind of prayer)
so you could chant "i smell like cat pee" in a monotone way and still be exercising different muscles inside..

think of shaking a chicken and seeing all its feathers flap off, with the feathers being your bodies impurites.
