The MMA fighter is using his body, which is what I'm saying, whereas the Calvin Klein model is just an appearance. In the movie he says "Is that what a man looks like?" What he's implying is that a man is beyond appearances. The body should be the byproduct of his lifestyle, his mission. A man that has a shitty lifestyle (9-5 office job) and then has a ripped body, is dealing with appearances. If you go deeper, he is implying that a ripped body should come from a fearless man, one who is not afraid to fight. In other words, the "fake" man has all those muscles, but you could slap the shit out of his scared ass. Just like someone who knows kung fu but in real life is helpless and will get killed.
Anyways, I can't dumb this down any further. Read some literature.
