Imagine if buses could do push-ups. Exercise equals good health, so cities would save a fortune on maintenance, right? Plus, we, as spectators would get to watch buff buses working out, which would be quite frankly awesome. Despite all of the missiles and other controversy, this double decker bus is pumped about the Olympic games this year.

It was created to promote said games by Czech artist David Cerny. This big red rig, nicknamed the London Booster, does push-ups with the help of an engine powering a pair of robotic arms. It does this with recorded sounds of grunting and groaning like an athlete working out.

If you want to take a look at it and get into a muscle flexing competition, it will be parked outside the Czech Olympic headquarters in London for the duration of the 2012 Olympic Games.
