Ryan Kwanten is stacked, all right! The 37-year-old actor went shirtless at the beach in Malibu, Calif., on Tuesday, Aug. 5.  

The True Blood hunk, who plays Jason Stackhouse in the hit HBO show, only wore low-hanging black swim trunks, showcasing his ripped torso and a "V" cut around his pelvic area.  

In 2011, Kwanten told Vulture that his buff body comes from a naturally active lifestyle.  

"I just work out for my own sanity, to be honest. I grew up in a competitive, sporting environment. It's just sort of part and parcel of who I am. I'm one of three boys, and the easiest way for my mom to deal with all of us was to kick us outside."

This summer, Kwanten made fans swoon on True Blood, making out with Alexander Skarsgard during a surprise gay sex scene (check out the GIFs!).
