Zac Efron Shows Off HIs Sick Abs While Working Out With Buddy Nina Dobrev — WATCH

Zac Efron showed off his rock hard abs while working out with his pal Nina Dobrev in a new video that Zac posted to his YouTube channel.

The video is part of Zac‘s new series Gym Time w/ Zac Efron where he plans to “train with celebrities, athletes, and interesting people” to get to know them better.

In other words, a recurring thirst trap.

The pair did some “side bends,” which their trainer, Johnny Fontana, explained are a great way for individuals to develop their obliques, which is how Brad Pitt got those sick lower ab muscles in the 1999 film Fight Club.

Afterward, Dobrev joked that after a mere 15 reps, her workout buddy for the day now looks just like Pitt. That’s when Efron pulled up his T-shirt, offering a glimpse at his muscular stomach.

“That wasn’t there before,” she joked, before adding, “You gotta work hard to…something else hard. You gotta work hard to play hard.” This flub definitely got Efron laughing.
