A world where Saitama trained so hard he went bald and broke his own limiter defeating every opponent with a single punch. OPM is both a satire of superhero culture and a genuine love letter to consistent training. The famous Saitama routine — 100 pushups, 100 situps, 100 squats, 10km run, every day, no rest — is legendary precisely because it's simple, consistent, and brutally effective.
Created by ONE and illustrated by Yusuke Murata, One Punch Man takes place in a world of monsters, heroes, and the Hero Association a ranked organization tasked with protecting humanity. At the top of that world, somehow, is a bald man in a cape who trained himself to the point where he can defeat any opponent with a single punch.
What makes OPM unique as fitness inspiration is its duality. Saitama's routine is deliberately ridiculous in its simplicity and yet it works within the fiction, and the real-world version is genuinely effective for building conditioning. Meanwhile, the S-class heroes offer serious physique and strength inspiration: Darkshine represents the pinnacle of hypertrophy, Bang shows that martial arts mastery compounds over a lifetime, and Garou demonstrates that adaptive, evolving training beats a static program every time.
The core OPM lesson: consistency beats complexity. Show up every day, do the work, and the results will come.
Every One Punch Man character available for training — all 8 already have complete training programs live.
The man who broke his limiter through 3 years of daily training. His program is simple, repeatable, and performed every single day without exception. No days off.
An S-class hero in his 80s who can move faster than the eye can follow. Bang's program is rooted in martial arts movement, flow, and the highest technical standard.
Garou's style evolves mid-fight. His program mirrors this: constantly varying stimulus, adaptive training, and the martial arts framework of someone who studies every opponent.
Genos trains his organic components relentlessly. His program focuses on functional strength, explosive conditioning, and the kind of mechanical efficiency that makes every movement count.
The most muscular hero in the association. Darkshine's program is pure hypertrophy high volume, progressive overload, and a focus on building the most impressive physique possible.
A direct, no-nonsense strength athlete. Tanktop Master's program cuts through the noise heavy compound movements, linear progression, and old-school iron work.
An unorthodox but undeniably powerful fighter. His program uses high volume and extreme density to build a body that can take punishment and keep going.
Fluid strength that adapts to any situation. Mizuki's program blends power lifting with athletic conditioning for a physique that performs as well as it looks.
100 pushups, 100 situps, 100 squats, 10km run every day, no rest, no excuses. The most famous training routine in anime history is also one of the most effective conditioning programs for beginners.
Saitama didn't do anything extreme he just never stopped. Three years of daily work compounds into something superhuman. The programs here reward athletes who show up every day over those who go hard once a week.
What feels impossible becomes normal with enough repetition. Every OPM program has a built-in progression system because standing still is the only way to never improve.
Yes with caveats. Saitama's fictional routine 100 push-ups, 100 sit-ups, 100 squats, and a 10km run, every day is an excellent conditioning template for beginners and intermediates. It builds cardiovascular endurance, muscular stamina, and basic bodyweight strength. Where it falls short is progressive overload doing the same thing every day eventually stops driving adaptation. OtakuAthlete's live Saitama program keeps the spirit of the fictional routine while building in the progressive challenge the original lacks.
Start with Saitama he's tagged Beginner difficulty, his full program is live now, and represents the simplest possible training structure in this universe: daily, no equipment, no complexity. The daily commitment builds the habit of training, which matters more than any specific exercise selection. Garou (Intermediate) is a natural next step once your foundation is built his full program is live too.
It can be excellent for it high-volume, high-frequency bodyweight work like Saitama's fictional routine burns significant calories, and the 10km run component alone is a major contributor. Paired with a moderate caloric deficit, daily calisthenics-style training is one of the more effective approaches for simultaneous fat loss and conditioning improvement. Weightlifting-leaning characters in this universe are better suited to body recomposition once their programs are published.
