Zac Efron has revealed the full glory of his six pack on the Miami set of Baywatch.

The actor, 28, went shirtless on the beach on Saturday displaying his new muscle man shape.

In addition to his stunning abs, he showed off huge shoulders and biceps and bulging arm veins. 

Oh boy! Zac Efron revealed how much he's bulked up for lifeguard duty in the movie reboot of Baywatch, currently lensing in Miami

Zac has been in a friendly rivalry with his co-star Dwayne 'The Rock' Johnson who has posted videos of himself pumping iron on social media in readiness for the film.

And it's clear the former High School Musical star can give the former WWE wrestler a run for his money.

In fact he's so buff Zac for a moment forgot he's supposed to be playing a lifeguard and channeled his inner Tarzan by swinging on a jungle rope.

Meanwhile, as Zac was perfecting his jungle swing, The Rock was getting a little pampering on set from his personal brow mopper.

As the 43-year-old sweated in Miami's tropical heat, an assistant dabbed his bald head with a towel cloth.

The actor and producer kept his muscled frame covered in his lifeguard costume of a blue short-sleeved top and red shorts.

The day before, Zac had kept his shirt on as he rehearsed and filmed scenes with co-star Alexandra Daddario.

The two were playfully flirty as they acted out an exchange between their characters. 

He was also seen swapping notes with The Rock before the cameras rolled on a somewhat heated encounter between their two characters.

Also on board for the big screen reboot of the iconic TV show are Kelly Rohrback, Ilfenesh Hadera and Priyanka Chopra with the movie slated for a 2017 release.
