Zac Efron Shows Off His Biceps In A Tight T-Shirt, Talks Doing First Car Racing Scene

On Set of 'Townies'
More from the set of Zac's newest flick.
Hi Zac Efron’s biceps!

The 25-year-old and his bulging biceps were spotted on set of his newest flick Townies! The actor showed off his frat pride in a tight white t-shirt and was seen sporting a tattoo of  some sort of fraternity symbols (we’re hoping it’s just for the movie).

This film seems to have a lot of what we like about Zac – his body! The actor was also recently seen in a robe showing off his chest and even completely shirtless posing in front of Abercrombie & Fitch!

Meanwhile, Zac’s other movie, At Any Price, we will see him racing cars! He revealed in an interview that he knew very little about NASCAR beforeshooting the film. He explained what it was like to film his first racing scene:

I was completely new to it. They just put me in a car and said, ‘Go!’ At one point, I got up to 140 miles per hour. It was a rush.

At Any Price also stars Dennis Quaid and Heather Graham and is now out in theatres.
