A London bus has been transformed into a muscle-clad machine that can do push-ups!

The double decker has huge arms stuffed with lots of wiring and hydraulic joints that allow it to move up and down like an Olympic athlete in training.

It even has groaning sound effects to make it seem like the bus is straining to complete its workout.

David Cerny, the man who designed it, has called it the London Booster.

The bus is on display outside the Olympic headquarters in London.
