Saitama’s strength is the central mystery of One Punch Man. He defeats any opponent with a single punch, yet the journey to that overwhelming power is defined by extreme simplicity rather than complex techniques. Understanding what did saitama do to get strong requires looking past the comedic surface to the brutal logic of his regimen. His method strips away all excuses, focusing on three core pillars: intense physical conditioning, strict dietary rules, and relentless consistency.
The Foundation: The 100 Push-ups, 100 Sit-ups, and 100 Squats Regimen
The most iconic part of Saitama’s training is his daily routine of 100 push-ups, 100 sit-ups, and 100 squats. This is not a casual workout; it is performed under extreme conditions to build a foundation of raw strength. He completes these exercises while living in a cheap, run-down apartment with no modern conveniences, adding resistance through the use of a heavy sandbag. The purpose is to condition the body to its absolute limits, forging muscle and discipline through sheer volume and mental fortitude. This routine strips fitness down to its most basic elements, proving that consistent bodyweight exercises can create god-like power when done without pause.
Saitama does not train in a climate-controlled gym with motivational music. He runs until he collapses in the summer heat and trains in the freezing cold of winter. This environmental stress is a critical component of what did saitama do to get strong. By forcing his body to adapt to harsh weather and physical exhaustion, he dramatically increases his stamina and resilience. This method ensures that any normal environment feels easy in comparison, allowing him to maintain peak performance regardless of external factors. The mental toughness gained from this suffering is just as important as the physical gains.
The Discipline of a Hero Diet
Physical exercise is only half of the equation; diet plays an equally vital role in Saitama’s transformation. He follows a strict regimen of eating only a single grocery store meal a day, focusing on balanced nutrition rather than indulgence. This controlled intake ensures that his body enters a state of caloric deficit, forcing it to burn fat and build lean muscle efficiently. The discipline to maintain this simple, healthy diet every single day highlights his commitment to becoming stronger. He treats food as fuel, avoiding excess that would hinder his progress rather than viewing meals as rewards.
Saitama’s strength comes at a price that is often overlooked in the pursuit of his abilities. He has lost his hair, his sense of taste, and the ability to get excited about anything. The monotony of his training loop—waking up, exercising, and repeating the same routine daily—has stripped him of ordinary human pleasure. This trade-off is the central tragedy of his character; he traded a normal life for the power to protect it. Understanding this cost adds depth to the question of what did saitama do to get strong, revealing that the answer is not just physical, but deeply personal and isolating.
The Unseen Factor: Consistency and Time
While the specific exercises are simple, the true secret lies in the unwavering consistency required to perform them. Saitama trained for three years, doing the same 100 reps every single day without missing a session. There were no shortcuts, no days off, and no magical supplements. The answer to what did saitama do to get strong is ultimately about showing up repeatedly over a long period. This mundane act of persistence is something few can maintain, which is why his strength is so rare. The timeline itself was the resistance, grinding away at his limits until he surpassed them.
