David Corenswet’s Intense Training Fuels Superman Sequel Buzz

David Corenswet has been spotted hitting the weights again, this time in preparation for his next outing as the iconic superhero. The actor, who made a splash with his debut as the Man of Steel, has been seen working out alongside his personal trainer, Paolo Mascitti, the same bloke who helped him bulk up for his first go in the cape. The latest gym snap, shared by Mascitti on social media, has sent fans into a frenzy, with many taking it as a sure sign that production for the much-anticipated sequel is right on schedule.

While updates on the project have been few and far between, Nicholas Hoult, who’s set to play Lex Luthor, previously confirmed that filming would begin in April. The recent photo of Corenswet and Mascitti together has been widely circulated by keen fans, eager for any hint that things are moving forward. For many, it’s a quiet but clear signal that the groundwork for the next chapter is well underway.

Corenswet’s Gruelling Regimen

Getting into superhero shape is no small feat. Corenswet’s transformation for his first turn as Superman was nothing short of dramatic. Under Mascitti’s guidance, he stuck to a strict training schedule and a hefty diet, reportedly consuming up to 6,000 calories a day. The actor managed to pack on 40 pounds, going from 200 to 240, with daily two-hour sessions focused on compound lifts and squats. Mascitti once mentioned that,

“half of his training had to be done over FaceTime.”

Now, seeing the pair back in the gym together ahead of the sequel is a testament to their commitment to getting the job done right.

Fans have been quick to show their support online. One punter wrote,

“With David Corenswet back in Superman shape and filming this April, the hype for Man of Tomorrow is real. James Gunn says this isn’t just a sequel; it’s a deep dive into Clark and Lex’s dynamic. Seeing David get back to ‘fighting weight’ makes me think the action in this one is going to be on a whole different level.”

Another added,

“This also means intense workouts, strict diets… all for the sake of delivering that perfect Superman performance. Respect!”

A third simply said,

“Rooting for you and your training, David Corenswet!”

Countdown to Cameras Rolling

Last time around, Corenswet’s training started five months before filming began. While it’s not clear exactly when he and Mascitti picked up their routine again, it’s no surprise to see him back in the gym with just over two months to go before production kicks off. The sequel, titled Superman: Man of Tomorrow, is set to hit cinemas on 9 July 2027, following the releases of Supergirl and Clayface in 2026.

Its spot on the release calendar means it’ll land ahead of The Batman Part II, which is due out in October 2027, more than five years after the first film.
