Peter Kavinsky, is that you?!
The star from the To All the Boys franchise appeared on the fitness Instagram profile of personal trainer Kirk Myers putting in work at the gym, and the gains were definitely showing in March.
The 24-year-old heartthrob has bulging muscles in preparation for his upcoming role as Albert Rothstein, a.k.a. Atom Smasher, in the DC Extended Universe's Black Adam.
During an interview with Australian radio show Smallzy's Surgery, Centineo explained how he bulked up to keep in step with the movie's star—Dwayne Johnson—by increasing his daily calorie intake to over 6,000.
"Last time I gained, I was eating 6,500 calories a day," he recalled, "but this time will not be as bad." At one point, he noted beginning his days with 12 eggs, steak, potatoes and a couple bowls of oatmeal.
Due to the ongoing coronavirus pandemic, the film's production was paused, which gave Centineo added time for his high-intensity workouts, two hours every day to be exact.
