How the WWE Legend Transformed Into a Superhero
When John Cena took on the role of Peacemaker in James Gunn’s The Suicide Squad and the spin-off HBO Max series Peacemaker, fans were blown away by how perfectly he fit the part. Cena didn’t just embody the sarcastic, morally-conflicted antihero with his acting chops—he also looked every bit the part of a comic book superhero. His physique was equal parts powerful, athletic, and believable for someone who could pull off larger-than-life action sequences.
But how did Cena prepare for the role? What kind of training went into the Peacemaker workout? And how can you apply some of his fitness principles to your own routine? Our team at Generation Iron is going to break down John Cena’s approach to training, nutrition, and recovery that helped him bring the DC character to life.
The Physical Demands of Playing Peacemaker

Unlike professional wrestling, where John Cena spent years performing choreographed matches with heavy stunts, acting as Peacemaker required a slightly different type of physical preparation. Instead of just focusing on size and strength, Cena needed:
- Functional strength for fight choreography and action stunts.
- Endurance for long days of filming.
- Aesthetic appeal to look like a comic book superhero on screen.
- Mobility and flexibility to avoid injury during complex stunt work.
Cena’s Peacemaker workout was designed with these demands in mind. It wasn’t just about lifting heavy weights—it was about looking the part and performing like the character.
John Cena’s Training Philosophy
John Cena has been training for decades, long before his transition into acting. Known for his disciplined approach, Cena follows a hybrid of bodybuilding and functional strength training. His goals have shifted from his wrestling days—he doesn’t need to bench press 500 pounds anymore. Instead, his focus is on maintaining muscle mass while staying agile and camera-ready.
Key principles of Cena’s training:
- Consistency Over Intensity – Cena trains almost every day but avoids burning himself out with unnecessary max lifts.
- Variety in Training – He incorporates bodybuilding-style hypertrophy workouts, Olympic lifts, and functional movements.
- Form Over Ego – Even as one of the strongest WWE superstars ever, Cena emphasizes technique.
- Longevity Matters – At over 45 years old, Cena prioritizes staying injury-free while still looking superhero-ready.
