The one thing more impressive than Zac Efron's body of work: His body in general!
The now-single 23-year-old former Disney star showed off his buff bod and brand new feather tattoo last week while working out shirtless on Manhattan Beach with buddy (and Brittany Snow ex) Ryan Rottman.
Efron recently packed on 18 lbs. to play a Marine in the upcoming flick "The Lucky One" -- and will next appear in an untitled action-romance where he'll play a "suburban kid who travels to Europe" and falls for a young woman with ties to the criminal underworld.
Zac also recently filmed scenes for the celeb-packed "New Year's Eve."
