Patrick Schwarzenegger shows off his muscles in a tank top while riding his bike to the gym on Tuesday (May 19) in Venice, Calif.
The 21-year-old actor/model was joined by his dad Arnold and some of his buddies for the afternoon workout session.
Arnold recently chatted with TheWrap about his use of social media and revealed what his kids think about it.
“The kids like it,” he said. “And a lot of people get encouraged by my age [to join social media]. They know I’m not a genius when it comes to all this technology, and they say, ‘well if he can do it and he uses it, maybe we should do it too.’”
