Zac Efron is Looking Ridiculously Jacked on Set of New Film ‘The Iron Claw’

No stranger to the iron paradise, Zac Efron is looking absolutely jacked at the moment. The 35-year-old actor has transformed his physique for the upcoming movie The Iron Claw, recently spotted wearing nothing but a towel and a fresh tan on the film set in Louisiana. As expected, the internet’s reaction didn’t disappoint.

Zac Efron will star opposite Jeremy Allen White (Shameless) and Lily James (Pam & Tommy) to portray the story of real-life wrestler Kevin Von Erich. Based on the true story of the Von Erichs, the film follows the rise and fall of the family dynasty that helped shape the sport as we know it today.

Playing the role of wrestling champion Kevin Von Erich required the 17 Again star to pack on some serious muscle meat. And it looks like he’s more than accomplished that goal, rocking some jacked arms and a defined chest on top of the shredded six-pack with bulging abdominals in the now viral on-set photo.

When the images first surfaced online, fans and jokesters went straight to Twitter to react – with most blown away by the site of his muscular frame. Check out the best reactions below.

The last time we saw Efron this swole was when he starred in 2017’s blockbuster Baywatch. The High School Music alum recently revealed in an interview with Men’s Health how the training and dramatic physical transformation process for Baywatch caused him to develop severe mental issues.

“I started to develop insomnia and I fell into a pretty bad depression for a long time. Something about that experience burned me out,” Zac said. “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.”

“That Baywatch look, I don’t know if that’s really attainable,” he elaborated. “There’s just too little water in the skin. Like, it’s fake; it looks CGI’d… 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, 2 to 3 per cent body fat.”

Let’s hope Zac has learned from his previous experience.
