A trademark London double-decker bus has been turned into an athlete doing push-ups to celebrate the Olympic Games opening in the capital this week.

Czech artist David Cerny bought the 1957 bus from an owner in the Netherlands. Weighing in at an impressive six tons, it is flexing its muscles in Islington throughout the Games. Cerny thinks it's a great way to celebrate the Games:

"There is one common exercise for every sportsman in the world and that is the push-up. I thought the push-ups would be perfect fun.

"The thing about push-ups is that on the one hand it is training for sport activities but at the same time it is also punishment in armies and prisons.

"So the push-ups are a very universal kind of movement, proving physical abilities, and that's why I like it."

Wiring and suspension tools help the bus move up and down on bright red arms, accompanied by recordings of a loud groaning voice and video projections in the windows.

The double-decker is set to be busting its moves throughout the Olympic Games.
