Zac Efron Goes Shirtless, Shows Off 'Buff Physique' On Yacht Getaway

Zac Efron is turning a yacht day into a headline moment. A photo shared by Just Jared shows Zac Efron going shirtless while relaxing aboard a yacht in Ibiza, Spain, and yes, his "buff physique" is front and center. The actor appeared laid-back as he leaned forward near the helm, wearing black sunglasses and a green baseball cap while enjoying time with friends on vacation. Dressed simply in swim trunks and nothing else, Efron’s muscular build was on full display as he soaked up the Mediterranean heat. The candid snap captures him mid-conversation, smiling slightly and looking completely at ease during the seaside escape.

The post quickly drew attention online, racking up thousands of likes. Many fans filled the comments with heart-eyes emojis praising his physique, including one user who expressed, "Stunning as always."

Over the years, Efron has transformed his body for roles in projects like "Baywatch" and "The Iron Claw," often speaking about the intense training and discipline required to maintain that level of conditioning. In fact, in a past interview with Men’s Health, Zac Efron opened up about the grueling preparation behind his wrestling role in "The Iron Claw."

According to the actor, rehearsing real wrestling moves ranked among the toughest challenges of his career, and the toll on his body was undeniable. “It was one of the most challenging things I've ever done, physically,” Efron admitted. “I was turning purple in parts, they would just cover it in makeup.”

The bruises weren’t for show. The physicality of the sport required full commitment, and Efron often left set battered after long days of choreography and contact.

If "The Iron Claw" tested his physical limits, "Baywatch" pushed him somewhere even more extreme.

In a candid interview with Variety, Zac Efron reflected on the intense regimen he followed to achieve his ultra-shredded look for the 2017 film, and why he wouldn’t do it again. Efron revealed he was taking diuretics, overtraining, and eating the same three meals every single day. He would wake up at 4 a.m. to work out, regardless of how late filming ran the night before.

“I started to develop insomnia, and I fell into a pretty bad depression, for a long time,” Efron said. “Something about that experience burned me out. I had a really hard time recentering. Ultimately, they chalked it up to taking way too many diuretics for way too long, and it messed something up.”

Looking back, he admitted the hyper-defined “Baywatch” physique wasn’t sustainable or even realistic. “That ‘Baywatch’ look, I don’t know if that’s really attainable. There’s just too little water in the skin. Like, it’s fake. It looks CGI’d," he said. "And that required Lasix, powerful diuretics, to achieve. So I don’t need to do that. I much prefer to have an extra, you know, two to three percent body fat.”

After opening up about the extremes he once pushed his body to, Efron has since shifted his approach to something far more sustainable. These days, Zac Efron still trains hard, but with a focus on longevity and mental resilience.

He’s embraced what he calls “mindful” training, incorporating foam rolling, self-massage, and regular ice baths into his routine.
