Simu Liu is back in the gym—and back in the fight—as he prepares for his epic return as Shang-Chi in Avengers: Doomsday.
While filming continues in London, the Marvel star has been spotted training hard and looking absolutely ripped, signaling that Shang-Chi isn’t just showing up—he’s showing out.
Recent images from celebrity trainer Dr. Ethan-Ira Mamuric’s Instagram show Liu training side-by-side with James Marsden, who’s returning to the MCU as Cyclops. The two were seen playing padel and posing for a post-workout shot, both looking like they’ve been living in the gym.
And honestly? It shows.
💪 Simu’s Physique Is on Another Level
Liu recently posted a mirror selfie on X (formerly Twitter), casually revealing a shredded six-pack, sculpted arms, and what fans are calling his “best shape yet.”
For fans who’ve followed his journey since Shang-Chi and the Legend of the Ten Rings, this transformation is something special. Back then, Liu stunned with his martial arts speed and lean frame. Now, he’s clearly adding more size and power—likely a sign that Shang-Chi is about to face his toughest battle yet.
“You’ve just got to get your butt out there,” Liu told Men’s Health about his original training mindset. And clearly, he’s still living that motto.
🥋 How He’s Training
Liu’s approach to fitness isn’t just about looking good on screen—it’s about performing. He’s blending high-intensity martial arts drills with strength training, explosive movements, and combat choreography to prepare for what’s expected to be some of Marvel’s biggest action scenes yet.
His workouts include:
- Banded deadlifts & sled pushes for raw power
- Box jumps & rotational slams for speed and agility
- Fight-based training to keep his moves sharp
- Intermittent fasting and carb-cycling to stay lean and camera-ready
It’s a mix of modern superhero science and old-school discipline—and it’s working.
🎬 Why It Matters for Avengers: Doomsday
Avengers: Doomsday isn’t just another Marvel movie. It’s shaping up to be a massive, multiversal crossover, with heroes from across the MCU—and beyond—facing off against Doctor Doom.
And Liu’s Shang-Chi? He’s right in the middle of it. Rumors suggest he’ll be part of Sam Wilson’s new Avengers lineup, fighting alongside characters like Spider-Man, Captain Marvel, and the X-Men.
Pairing him with Marsden’s Cyclops also has fans speculating: will they clash? Team up? Train together? Either way, it looks like Marvel is building some powerhouse pairings for this high-stakes installment.
🧠 Behind the Scenes, Liu’s Still Just a Fan Like Us
What makes Simu Liu so fun to root for isn’t just his on-screen skills—it’s his off-screen energy. He’s vocal about how surreal it is to be part of the MCU, and he takes his role seriously. Not just for himself, but for fans, for Asian representation, and for the legacy of the character.
And judging by his current grind? He’s not taking this opportunity lightly.
📅 Avengers: Doomsday is now filming and is set to explode onto screens as part of Marvel’s Phase 6.
With Simu Liu transforming his body, sharpening his skills, and embracing the role like never before, it’s clear: Shang-Chi is ready for war. And we can’t wait to see it.
