From people having private dinners to others shamelessly pleasuring themselves, you'll see just about anything on the New York City subway. This man, who turned an M train car into a gym because staying fit is of the utmost importance to him, falls somewhere in the middle of the spectrum.
For all we know, more pressing matters might have cut into his traditional workout time, so he went to semi-obnoxious extremes to get a quick pump. On top of that, he did with shades on, because style is just as important as execution.
He could probably make some bread by starting a "Subway Workout Plan" series. He should definitely look into that.
Oh, and just because:
New York City—you have to love it.
