Zac Efron showed off his ripped physique as he went shirtless at the beach while spending some quality time with his family

While taking their younger sister Olivia, four, to the beach, the 36-year-old High School Musical star and brother Dylan, 32, were every inch the doting older siblings as they swung her around on their arms in the ocean

The trio appeared to be having the time of their lives as they splashed around in the water and shared their love of nature with Olivia

In the footage, he put him washboard abs on full display as he rocked just a pair of black swim trunks and a baseball cap.

Following his mother Starla and father David’s split, the the Greatest Showman actor’s dad welcomed Olivia as well as another son, named Henry.

Zac and Dylan, who are only four years apart, are extremely close despite ‘always fighting with each other’ when they were kids.

‘[T]hen once I graduated college, Zac really took me under his wing and let me live with him when I got my first job in Los Angeles,’ Dylan told BroBible in 2021.

He continued: ‘He really became that older brother, and that’s when I would say we grew closer than ever. Our relationship was something that developed more as we both became adults and stopped fighting so much.’

Dylan has established his own career in Hollywood outside of his brother’s famous shadow, serving as a physical production coordinator on several films including American Sniper and The Accountant.

He also was a producer on his big brother’s 2020 Netflix series Down to Earth With Zac Efron, where the Lucky One star traveled across the globe to find the road to better health and a more eco-friendly mindset.

While the Hairspray star has proven to be a fine actor in his own right, Dylan has demonstrated more of a strength as a filmmaker.
