It would be nothing short of amazing if one of these 'experts' actually worked out at least just once in their lives so they might have some knowledge as to what they're talking about.. 
what has actually working out got to do with picking the most pleasing physique?
how does a person prepare for looking at a bunch of dudes in trunks and judging who appears the best?
if you think that any credibility is enhanced by a person who also trained then you are misguided.
