That's pretty much my motivation orangina. I havent felt at all body confident since 2003 and want to feel confident enough to wear a bikini on holiday with bf.
I'm small and thinish already but very saggy and flabby around the edges(with more than a few inches to pinch on belly) so could look a lot better with some toning. Also it's embarrassing how unfit and weak I am.
So reason 1 = vanity
reason 2 = health 
I havent done it yet today, but did eat the ferrero rocher while doing a horrible bit of work so am going to do it now. Or something at least.
