So, for example, if I were to do lots of arm exercises, would the fat that I burned off predominantly come from my arms, or would the energy required come from body fat elsewhere? So, in order to get rid of flab, is it better to focus exercise on the regions within ones body that are adipose rather than already muscled, or will exercise that uses those muscled areas burn off fat from other areas?

Does that make sense?  []

And obviously I'm asking for my fat chum, and not me post xmas....

I see no reason why fat would burn predominantly off your arms if you were to do lots of arm exercises. Tell your chum [] to have a look at: http://www.bodybuilding.com/fun/bbmaintrain.htm
There are some really good articles and training exercises there []
