Patrick Schwarzenegger has a long way to go before he gets as buff as his famous father -- but the young model is definitely bulking up.
Maria Shriver and Arnold Schwarzenegger's 19-year-old son is on a mission to put on some muscle and shared a shirtless photo from the gym.
"Early morning pump! Who is getting into shape for summer??!! Gonna gain 7 pounds this summer," Patrick tweeted while showing off his impressive abs.
You can see more of Patrick when he makes his film debut in "Grown Ups 2" this July.
FYI: Here's what Arnold looked like when he was Patrick's age. Yep, he was never not buff.
