David Corenswet’s Intense Training Fuels Superman Sequel Buzz

David Corenswet has been spotted back in the gym, and the sight of him working out with his trusted trainer has sent a ripple of anticipation through the Superman fanbase. With filming for the next chapter in the DCU saga scheduled to commence in April 2026, the actor’s renewed commitment to his physical transformation is being taken as a promising sign that production is moving forward as planned. The image, shared by celebrity trainer Paolo Mascitti, quickly made the rounds online, with fans dissecting every detail as evidence that the wheels are turning for the sequel’s launch.

While updates on the project have been rather thin on the ground since Nicholas Hoult, who is set to portray Lex Luthor, confirmed the production timeline last November, this recent glimpse of Corenswet in training has reignited speculation and enthusiasm. For many, it’s a quiet but clear indication that the groundwork for Superman: Man of Tomorrow is being laid, and that the lead is once again preparing to don the iconic suit.

Physical Transformation and Fan Reactions

Corenswet’s journey to embodying the Man of Steel has been anything but casual. Under Mascitti’s guidance, he previously undertook a demanding regime, reportedly consuming up to 6,000 calories daily and pushing his weight from 200 to 240 pounds. The actor’s routine included two-hour sessions focused on compound lifts and squats, with a significant portion of the training conducted remotely via FaceTime. Now, seeing the pair reunited in person ahead of the sequel has only heightened the sense of anticipation among supporters.

Fans have not been shy in voicing their excitement.

“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,”

one enthusiast remarked on X/Twitter. Another added,

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

A third simply offered encouragement:

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

Behind the Scenes: Preparation and Production

Last time around, Corenswet’s training began five months before cameras started rolling. Although it’s unclear exactly when he and Mascitti resumed their sessions for the sequel, the timing aligns with the expected production start in just over two months. The sequel, set to premiere in July 2027, will follow the releases of Supergirl and Clayface, and is positioned to hit cinemas ahead of the next instalment in The Batman series.
