How Does Genos Train to Become as Powerful as Saitama?
When it comes to Genos, a cyborg and Saitama’s disciple, the question arises: how does he become as strong as he is? The explanation given is quite astounding: 100 push-ups, 100 sit-ups, 100 squats, and a 10km run every day until his hair falls out, transforming him into a stronger being than any other living creature in the One Punch Man universe.
Most people may find it hard to believe, but Saitama’s rigorous training routine has made him incredibly strong and virtually invincible. However, who really has the time or inclination to work out like this every day?
For instance, in Genos’s case and within the scientific community at the Hero Association, this explanation may seem absurd and inaccurate. Even the most dedicated individuals cannot compare to Saitama’s strength.
Moreover, Saitama possesses other abilities that cannot simply be explained by his training. For example, he can move faster than the eye can see or even launch himself into space.
So, what events have led to this phenomenon? Let’s examine two hypotheses that could potentially explain this transformation!
1. Is Saitama a Human or a Monster?

One theory suggests that Saitama is not a human but rather a monster. The question remains: how can he escape from creatures like Deep Sea King without getting injured?
The intense training he undergoes could hardly account for his status as the strongest anime hero of all time. This leads some fans to speculate that Saitama might indeed be a monster.
In the One Punch Man universe, many heroes initially appear as ordinary people who constantly push their limits. For instance, Blackluster achieves immense strength through rigorous training, while Speed-o’-Sound Sonic never stops enhancing his speed and battle skills.
Additionally, a human can become a monster if they push beyond their limits (either intentionally or unintentionally) to protect themselves. Throughout the series, it is clear that Saitama’s appearance has changed significantly since he began training.
No other monsters, whether human or extraterrestrial, can compare to the extraordinary feats achieved by Saitama. Does this mean Saitama is a monster in the traditional sense?
2. Saitama Has Broken His Own Limits

The latest theory from avid fans suggests that Saitama has indeed broken his own limits, which sounds compelling and is supported by many enthusiasts.
So, what are these limits that Saitama has surpassed? In the manga, Professor Genus from the Hero Association explains that all organisms have growth limits, referred to as “limits.” If a creature exceeds these limits, it risks becoming a monster.
Thus, Saitama’s immense strength could very well be attributed to his ability to surpass these personal limits.
What does this imply about Saitama being a monster? According to Professor Genus, a human can become a monster due to abnormal changes caused by factors such as environment, bad habits, pollution, and genetic mutations.
In the manga, a human might surpass their limits through extreme experiences like combat, as demonstrated in the intense battles against Garou. Professor Genus speculates that Saitama may have pushed his limits through a rigorous training regimen prior to becoming the hero he is now, with the only visible change being his lack of hair.
