I want to know the answer to the following question:
How much time did Schwarzenegger have to train for the 1975 Mr. Olympia competition?
All the background I'm provided with is that "Months before the 1975 Mr. Olympia contest, filmmakers George Butler and Robert Fiore persuaded Schwarzenegger to compete, in order to film his training in the bodybuilding documentary called Pumping Iron.". Is that enough to answer the question?
