His father found fame as a body builder before becoming a hit on the silver screen. And it seemed that 18-year-old Patrick Schwarzenegger was determined to follow in Arnold's footsteps as he embarked in a day on intense training yesterday. Wearing shorts and trainers, the youngster ran alongside a personal trainer near the family's Brentwood home. The teenager looked in peak physical fitness as he jogged along in the Los Angeles sunshine. He also used a wall to perform some press ups and was also spotted using a chin-up bar with ease. His father Arnold famously came to America from his native Austria at the age of 21, where he took part in several body building competitions.
