When it comes to transforming into an iconic superhero, for example, Superman, most of us would expect a grueling regime filled with rigorous workouts. Did we forget to mention those strict diets? Of course, that’s also a requirement, after all, donning the role of the Man of Steel is not a small feat.

But for David Corenswet, who is set to play Clark Kent in an upcoming project, the journey to becoming Superman was anything but conventional. James Gunn’sSupermanis scheduled for release in 2025, and just lately, DC fans have gotten the first glimpse of the character’s iconic costume.
Celebrity PT Paolo Mascitti, who teamed up with Corenswet to help him bulk up for the role, teased that the actor didn’t set out to beat Henry Cavill’s breathtaking physique from the previousSupermanflicks. Instead, Corenswet focused on becoming the best version of himself and providing his own unique spin to the iconic character.

Rather than tryingto imitateHenry Cavill’s Man of Steel physique, Corenswet, accompanied by the masterful guidance of celebrity personal trainer Paolo Mascitti, established his own path to phenomenal fitness. And this path acknowledged his human quirks, like a distaste for lunges along with a penchant for cereal.
In a recent unfiltered chat withGQ,Mascitti, renowned for shaping Hollywood’s finest, revealed the effortsThe Politicianstar has put into preparing for the role—efforts that went beyondeven the loftiest expectations:

“He was on around 6,000 calories a day and his diet was strict, but not as strict as I would have liked. Half of his training had to be done over FaceTime and half in person as he wasn’t in Los Angeles all the time. We’d speak remotely and I’d ask him about his diet and he’d be eating cereal!He’d ask, ‘What’s wrong with cereal!?’ But that’s why he’s the perfect Superman, he has a realistic expectation of himself and the role.”
But even James Gunn’s Superman has something he doesn’t enjoy doing. Mascitti admitted that Corenswet’s true weakness was his dislike for walking “lunges”, but his dedication to the role never wavered:

“He isn’t the biggest fan of them, but he does it. He’s great at squats, but he just doesn’t enjoy lunges.”
Mascitti could not resist praising Corenswet’s will and endurance while complimenting Gunn on his splendid casting!
