No pain, no gain!
There are plenty of things you can do to entertain yourself during long flights. You can read a book, fall asleep, watch a movie on your tablet, fall asleep, or read the plane safety card a million times. Or if you’re anything like this guy, you can drop down to all fours in the plane aisle and start doing pushups.

Wait, that last thing doesn’t make any sense. If planes cared about your gains, they’d have dumbbells. Also, this guy is doing his exercises at the front of the plane where the cabin crew does most of their work. Way to make other people’s jobs harder, guy!
