Hmm the debate on whether 'burning fat around one's middle' is focused by doing a specific exercise (in this case pull-ups/crunches) is a bit of a placebo IMO. It will as you say strengthen and help look toned.
I am intrigued though how you do "4 sets of 20 when out running"...
You obviously don't do these exercises because if you did you wouldn't write what you did. How big is your girth?
