A first in public transport, the unconventional machine was installed at the Moscow subway station to promote the 2014 Winter Olympics to take place at Sochi, Russia.
As part of the initiative, riders can receive a free ticket by standing in front of the machine's camera and performing 30 squats or lunges.
The machine proved popular in its first few days of operation with many taking up the challenge, as shown in footage posted to YouTube this week.
Seriously, this is absolutely amazing! Essentially, you get a free ticket for doing some exercise.
