I would never open up a hardcore gym, as a metrosexual haven with a hundred cardio machines would do a lot better financially. Everybody knows that metrosexuals will rarely continue but they'll keep paying because they're imbeciles and serial posers. You don't have to go to gym but you've got to be a member of one..
I'd sell those idiots overpriced water and supplements too(stocking bee pollen from Vince Goodrum).
I'd call it something like "Club 68" as weak metrosexuals will be seduced by the fact they will be a member of a club. 68 because it immediately is recognised as the number before 69. Sounds stupid but will likely sucker them in.
And finally I would hire a full faux hawk toting staff to canter around and look like they are doing something.
I'll be rich!
