Unca Vali's quick and dirty way to learn flutters:

You need to let your body know what movement you want it to make, right? Right.

Flutters aren't a natural movement for our bodies, right? Wrong.

Fake doing a hiccup... I'll wait. ::files nails::

Watch your diaphragm jump in the appropriate manner when you hiccup.

That is one flutter (a flut? ;-))) If you learn at first to hiccup repeatedly, you are learning to breath and close your glottis (in your throat) that stops up your throat. That stopping up of the airways causes a vaccuum in your chest cavity which sucks your diaphragm upwards. You then engage your stomach muscles to try and pull against the vaccuum. Therein lies your flutter.

Once you are comfortable, you need to build up speed and strengthen the muscles so that the flutter looks and gets bigger. If you start practicing now, you will have a spiff flutter in a year and half.

Hereing endeth the lesson...

Who practiced flutters while showering, brushing his teeth, taking the train to work...

This posting above was addressed to the girl whos chest starts moving. Sometimes my postings get posted where I clicked for them sometimes further down, it is a hit and miss thing withy tribe, strange. I hope, this one will go right under the one it relates to...

When standing in the freezer section your natural impulse is to hold your breath and rapidly contract/release your diaphram. From a practical perspective the cold pretty much isolates the action for you, all you have to do after that is remember how you held your body when you want to do it again. You'll still have to develop the muscles but being aware of how to isolate it is the important piece.
