The 27-year-old hunk - who is famous for showing off his muscles in movies - has confessed he enjoyed taking a break from working out to play a skinny DJ in his latest movie.
Speaking at the European premiere of 'We Are Your Friends' at the Ritzy Cinema in Brixton, London, Zac told BANG Showbiz: "I guess to be more authentic, I had to straighten up.
"We were running a lot. Even in the movie we were doing running shots every day, so it just kind of happened naturally.
"But that was kind of fun. I'd never done that. Everyone seems to be bulking up ... It was fun to go backwards and play a DJ. A sort of skinny, svelte guy. It was fun."
However, the 'That Awkward Moment' actor will soon be back in the gym following the news he's to star alongside Dwayne 'The Rock' Johnson in the upcoming 'Baywatch' movie.
Asked how he plans to bulk up for the role, he added: "I'm not sure. I'm just going to be swimming. I'm gonna outswim The Rock, man!"
Also in attendance at the premiere were Zac's co-star, Emily Ratajkowski and director Max Joseph.
