Patrick Schwarzenegger son Arnold Schwarzenegger Maria Shriver bathing suit ocean beach sand shirtless barefoot

Patrick Schwarzenegger enjoyed some time with the boys out in Malibu over the weekend ... going shirtless and soaking in the sun!

Even though Arnold Schwarzenegger and Maria Shriver are going through a very public divorce, their 17-year-old son seems to be handling things pretty well. Aside from trips to the beach, Patrick has also been staying busy with his security job at The Grove in LA.

After seeing these photos of Pat showing off his sculpted physique, we have a feeling the young ladies will be going in for the attack.

Patrick's mom, Maria, was also taking a stroll in the sand ... check out our exclusive video below, and see more of Patrick and his buds after the jump!
