A good friend of mine and very recently new pro bodybuilder works for a forclosure company down here in south florida.
They have genetics that we just dont have. I have trained and partied with him many, many times. He eats alot, trains like most of us but recovers and grows at a rate that is just phenomenal...
So yes, besides sponsorships and contest prizes, most of them HAVE to have a career to fall back on...
