It also depends on the idea of an abdomen having a resonant frequency in the first place.
With all the gooey stuff slubbing around in there the damping factor is almost certainly going to be well over unity and in that case, chickabiddies, there ain't no resonance.

There can be an overall resonant frequency.
The catch is that it will vary from person to person, and also from condition to condition- did you eat recently? did you take a major shit? is your bladder full?

So there isn't a magic frequency that will work all the time, or even one that will work most of the time.

Too bad, as that could have some really interesting applications.
