If you've had to cut the gym from your budget, Urlesque reminds us that we're all already paying for an on-the-go workout space: the subway. They've compiled some videos of subway exercise methods from cities all over — the best and most comprehensive one can be found here.

Stretches, pull-ups, squats... the possibilities are endless for those willing to do just about anything in front of their fellow straphangers. We wonder if anyone's tried yoga while underground, or tossed around the ol' medicine ball.

Get some more tips on subway workouts here. Personally we prefer getting off a few stops early and walking, because really, could you picture yourself doing this on your line?
