Jiu Jitsu is the art of using strength! In the photo, we see two of the very best, but what top competitor isn't strong? What top competitor isn't muscular nowadays? Although there might be one or another, the overwhelming majority are buff. If that is true, where does the myth technique always beating strength come from? I'll give my reasons with a brief explanation.
1. Mr. Helio Gracie never had any strength and he beat much stronger opponents.
This was a "Vale Tudo" context where his opponents didn't fight, and many times they didn't even know the Gentle Art. The combat was not "Jiu Jitsu vs Jiu Jitsu". It's worth remembering that he tired them out to beat them. In other words, he beat his opponents when they no longer had any strength or any significant muscle explosion in their favor.
2. Royce in the first UFC tournaments.
Royce did basically what his father had already done 60 years before. He eliminated the distance, controlled his opponents, either took or was taken to the ground and once he was there he kept himself safe with his positioning, without measuring strength against giants like Dan Severn, Ken Shamrock, and others. When the chance presented itself, he submitted them. As the great master Hélio Gracie said:
"The mousetrap never chases the mouse. It simply shoots when the mouse steps on it".
3. Jiu Jitsu Self Defense applied in real situations against stronger, untrained, and often drunk aggressors with success.
All these situations differ from sport Jiu Jitsu where athletes have similar skills. A simple example would be blue belt men, almost always beating clearly more talented, skillful, and higher-ranked women. Is it because men are invariably better than women in Jiu Jitsu? The answer is obvious! The advantage men have naturally is the levels of testosterone, their percentage of muscle mass, and their bone structure.
Yes, competitive Jiu Jitsu is technical, but strength is essential for a successful career.
