Patrick Schwarzenegger showed off his buff physique in a shirtless picture posted to his Twitter page over the weekend.

The picture, featuring Schwarzenegger, a 19-year-old aspiring actor flexing his guns, is captioned, "Early morning pump! Who is getting into shape for summer? Gonna gain 7 pounds this summer." Schwarzenegger was spotted shirtless on the beach in South Beach, Miami back in March looking fit, but not quite as ripped as he does in this latest picture.

Schwarzenegger, the son of former body builder and action star Arnold Schwarzenegger and Maria Shriver, will soon be seen on the big screen in Grown Ups 2 on July 12. He’ll be playing a fraternity brother alongside Taylor Lautner in the comedy, which also stars Adam Sandler and Kevin James.

Schwarzenegger will begin filming his next film, Dear Eleanor, this summer in Denver, Colo. The feature, directed by Kevin Connolly, will follow the story of two young women travelling across the country in 1962 to meet their hero, former First Lady Eleanor Roosevelt. It will also star Jessica Alba and Luke Wilson.

Last month, Schwarzenegger, who’ll be a sophomore at USC in the fall, made headlines after getting thrown out of an L.A. club for allegedly throwing ice cubes at the DJ.
