You're all missing the point. The line is an ode to the short lifespan of a boxer's career. He's quite handsome and stylish when he starts out, looking very much like some delinquent that is willing to take a lot of hits. The fact they only evolve by climbing the largest mountains only to end up an ugly beaten abomination represents the sacrifices one makes by committing to the boxing lifestyle. The end result is parkinson's, a busted face, and mental derangement comparable to some animal. All they have to show for their life is their brute strength and martial ability, making them fit as boxing trainers as shown by the boxing mitt claws. All in all, the line is not meant to be visually appealing, it's meant to portray the reality of these fighters that throw themselves into the thick seeking those moments of glory only to be quickly forgotten.
