The apple doesn't fall from the tree.

Patrick Schwarzenegger unveiled his impressive six-pack abs on Twitter Friday.

"Early morning pump! Who is getting into shape for summer??!! Gonna gain 7 pounds this summer," Schwarzenegger, 19, wrote.

Schwarzenegger is the son of former bodybuilder and California Governor Arnold Schwarzenegger and journalist Maria Shriver.

The younger Schwarzenegger appears to be embracing fitness wholeheartedly. Last month, he tweeted a photo of his pantry stocked with healthy foods, including grains, water, and Welch's Fruit Snacks.

Like his dad, Schwarzenegger has been bitten by the Hollywood bug. He next appears in the Adam Sandler comedy sequel Grown Ups 2, which will hit theaters in July.
