hmm well i wouldnt go through the fuss unless someone feels you have potential as a model, or loosing that weight could be pointless. i was recommended to go and they said i was perfect except few inches to short and my figure wasnt boy-ish enough.
i wasnt fat you just need to have no curves no boobs no ass. you need a strict diet that you must stick to and a lot of will power. exercises would have to be yoga, pilates and general exercises that pretty much just tone you.
good luck.
