Zac’s had abs forever! Back in 2014, he dazzled fans at the MTV Movie Awards, after Rita Ora snapped off his shirt when presenting him with the award for Best Shirtless. That prize was much deserved.
The following year, Zac showed off his chest on the set of Dirty Grandpa.
Sorry Robert DeNiro, Zac’s giving you a run for your money!
How is he such a stud?! Zac basically never needs to put a jacket on, and the world will be totally fine with that.
And Zac doesn't just look phenomenal, he also does his own stunts. Is there anything he can't do?
Now let's get to Baywatch! He shocked the entire world with this transformation. Of course, Zac was obviously already in amazing shape over the years but this is just a totally different level.
Forget a six-pack. Zac literally was rocking an eight-pack. Guess you have to go extra hard or go home when co-starring with The Rock!
According to Zac’s trainer, Patrick Murphy, the actor reached 5% body fat after just 12 weeks of training.
And he didn't just look like a lifeguard, he had the strength and agility of one too!
Now that we've stopped drooling, we wish Zac a happy 30th birthday!
