The Efron genes run strong.
Zac Efron sent hearts racing after posing a series of shirtless snaps alongside his younger brother, Dylan Efron, to Instagram Friday.
The hunky siblings looked ripped as they posed in their swim trunks after enjoying a day of boating in Coeur D’Alene, Idaho.
While Zac, who wore palm tree and crystal pendant necklaces, showed off his chiseled abs in navy patterned shorts, Dylan opted for two-toned trunks.
Zac, 35, and Dylan, 31, both flashed big smiles for the camera despite the gloomy weather.
In the second snap, the former teen heartthrob fixed his hair after emerging from the water.
Zac also included photos of himself golfing — and getting swept up in a wave — in the carousel, which he simply captioned, “8/31/23.”
The thirst traps sent the “High School Musical” star’s 61 million followers into a frenzy given his lack of social media activity throughout the summer.
“saving *respectfully*,” one user commented, while another gave props to the pair’s parents, writing, “Nice genes, dad.”
