What a swinger! Zac Efron shows off his muscular chest and prowess for sports on the set of his new movie Townies

Zac Efron was in fine form.

The 25-year-old heartthrob set pulses racing as he strutted bare-chested with his shirt wide open while practicing his game on the Los Angeles set of Townies on Tuesday.

Zac, who plays a frat boy in the comedy, alternated between swinging a baseball bat and bouncing a basketball during what looked like rehearsals.

Feast your eyes: Zac Efron strutted his fine physique in unbuttoned shirt and grey track trousers on the Los Angeles set of his new film Townies

All eyes were not on the object in hand but on Zac's sculpted chest and six-pack abs, which looked like a work of art in the sun.

Zac was getting ready to shoot a scene, sprinting around in flip flops - although sometimes barefoot - and grey track pants that were tugged down slightly to reveal his shorts underneath.

The young actor was surrounded by beer cans, which wasn't surprising considering he plays a college boy whose antics affect the lives of his neighbours.

Swing away: There's no mistaking that the former High School Musical star is all grown up

Turning up the heat: Temperatures in the City of Angels soared a few degrees as Zac took up the basketball

Zac broke his hand last month during a fight sequence with his co-star Dave Franco, but his injury seems to have healed nicely.

The blue-eyed star explained what happened during a recent appearance on Live With Kelly And Michael.

'I broke it a couple days ago on set during filming, it was during a stage fight with Dave Franco,' Zac said at the time.

Going pro: Zac showed off his skateboarding skills too

Cool dude: Zac held his speed and his balance atop the skateboard

Break time: The star took time out for a soft drink on the porch

'I had to go back to work so I couldn't really wear a cast. So they [the medics] put like a titanium plate in it and a bunch of screws.

'I don't know why I'm telling you this. My hand in theory is back to normal, it just looks really gross.'

The film also co-stars Rose Byrne, Seth Rogen and Lisa Kudrow.

Ball boy: Zac seemed keen to prove his mettle with a basketball as he fooled around on set

Missing a trick: Rather than being an actor perhaps he should consider joining the Harlem Globetrotters

A minor adjustment: He was also caught out carrying out an unfortunate maneuver

Rose was spotted crossing the set while wearing a dark robe over navy sweat trousers and flip flops.

At another point, Rose and Seth were standing on a porch preparing to film a scene, and Rose was also holding a baby carrier.

Dave Franco was spotted looking handsome in a blue plaid shirt as he joked with some crew members.

Wrapping up: Rose bundled up in a robe between shooting scenes

Lightening up: Dave Franco enjoyed a laugh with some crew members

No doubt that he is a good looking guy but I think he tries a bit too much at being a "sex" symbol.

Nothing wrong with being average height, who needs some bug giant to climb. Also some celebrities choose to keep their private lives private, not everyone wants to put their business out to the world like a Kim Kardashian. I respect that he's keeping whatever and whoever he's doing out of the limelight and that fact that he's letting me droll over that gorgeous chest.~~~~~~~~ NNic21 , Redford, United States, 08/5/2013 20:11~~~~~~~~It's ALL AWESOME if you like short men . My fiancee is 5'10 and likes tall men. Being a 6"3 is not a bug giant but a normal height for a man, and even among us it's still not that tall. Just saying Tthe little guy looked tiny next to me and my brother who is 6"1. Good luck with with the drooling on his chest, knock yourself out and enjoy. LOL
