Not enough change lying around to buy a ticket for the Moscow Metro? Don’t worry, just loosen up your legs and get in line at the station’s newest ticket machine.

In the spirit of the upcoming Winter Olympics, the Russian Olympic Committee has installed a ticket machine to promote healthy lifestyles. If a would-be passenger can perform 30 Squats in two minutes, he or she gets a ticket to ride.
