I have a friend who is super into fitness who, years back, had done some videos about all of the many ways he is able to workout in an airport while waiting for a flight. It's not that hard. You don't need a designated workout area.

*internal screaming* I'm so fucking sick of these people. Just walk around the airport like a normal person if you need to stretch your legs my god...
