Set in '93?
In the intro to the movie it is White Goodman's commercial for Global Gym. Towards the end it shows a picture of White overweight with the caption "White Goodman 1987" and the voice over says it was him 6 years ago. Meaning, it's 1993. Or the same fictional commercial has been airing in the fictional universe for nearly a decade. It can't be set in '93 because of the Lance Armstrong scene towards the end.
