Noah Centineo has given fans a glimpse at his impressive physical transformation as he prepares for a new role in the latest addition to the DC universe.

In a series of Instagram videos shared by Myers on Wednesday the actor’s progress is evident as he works out shirtless, with his slender frame significantly bulkier and nicely defined. 

Centineo has made dramatic changes to his diet and lifestyle in order to keep in step with imposing co-star Dwayne  Johnson, who takes the film’s titular lead.  

However the American star admitted it isn’t the first time he’s bulked up during an interview with Australian radio show Smallzy’s Surgery in February.

‘Last time I gained, I was eating 6,500 calories a day,’ he recalled, ‘but this time will not be as bad,’ he explained.

Centineo, who previously starred in Netflix romantic comedy All the Boys I’ve Loved Before, also revealed he has been visiting the gym for ‘two hours every day’ for high-intensity interval training sessions.  

In March 2020 Noah revealed he had already gained ’30lbs of lean muscle tissue’ for the role.
