I want to know the answer to the following question:
Which part of his body did Schwarzenegger work to develop with Coach Bennett?
All the background I'm provided with is that "Schwarzenegger then flew back to Munich, training for four to six hours daily, attending business school and working in a health club (Rolf Putziger's gym where he worked and trained from 1966–1968), returning in 1968 to London to win his next Mr. Universe title.". Is that enough to answer the question?
Answer: no
