bro zoro trained and became stronger than regular humans, does not mean he would become that strong by default use your common sense. so why was young zoro losing to that girl.
or why did zoro become exponentially stronger in just 2 year? (it is because he trained if you want me to spell it out for you)
Zoro can physically stop Hakai
Physically overpower Kaido with 30 broken bones
Physically bust mountains
Physically send a robot that is the peak of creation that put Blackbeard on life support flying and swatted him away like a fly
Physically swatted away awakened Zoan much stronger than Lucci Physically (Giraffes are stronger than Leapords)
He Physically stopped dragon bigger than Moby Dick that swatted away Luffy literally like a fly, exact same version of Luffy matched jinbei Physically
Jinebei is NO WHERE NEAR zoro Physically much less Mihawk
