Arnie's dad disapproved of his bodybuilding

Arnold began lifting weights aged 15 and won the Mr. Universe title when he was 20, before going on to be named Mr. Olympia seven times.

However, his father Gustav thought his son was "egotistical and selfish" for being a bodybuilder.

He recalled: "He also didn’t understand or approve of my interest in bodybuilding. He thought it was egotistical and selfish. 'Why don’t you chop some wood instead,' he would say, 'you can get big and strong that way and at least then you will have done something for somebody else.'

Then there were the times he would come home drunk after work and hit us. Those nights were very hard."
