Adhere to the norm
Just another out of a seemingly infinite amount of media which all points to the fact that we should all adapt ourselves to fit the society, involving personal fitness, training social skills, etc.
But this time it's different, this time the only incentive for this person is nasty sex with hot women, which is THE reason to get into shape if anything. Prolonging your life? *beep* that, it's only to get laid, lol. :)
Of course this leads me to think that he could have gone a totally different route though. One guy mentions that he has a huge dick, he refers to him like John Holmes, lucky *beep* douche btw. So he could cut right to the chase, literally. He could set up his own porn website, just hire a bunch of random women to suck him off etc, then try to cover the cost of the movies by selling the videos online.
As I am almost as perverted as this guy myself and being somewhat of a porn connoisseur I am pretty sure he could make it work financially.
But they do touch on the subject of prostitution (which is similar to making gonzo porn) in the movie and I dunno, I'm kind of ambiguous about it, but basically it should be an option if you are desperate enough, like this guy.
