I'm looking for manga about fighting, martial arts where the main character is already powerfull or where the main char is training to get strong, I don't wan't to see people who are losing in a fight and suddenly get way stronger because of whatever mental reason,(like having flashback, seeing his sick sister).

AIKI
Its... theoretically realistic

Also History's Strongest Disciple Kenichi is realistic to a point...
Holyland is cool.

These may help?

Ares?
im like 20 chapters into it and it dont seem that way (yet)

shamo should be right up that alley at least untill the entire honk kong arc.

-Shamo
-Ultra Red
-Hajime no Ippo
and ya Holyland is pretty good.

Most mangas by HAMORI Takashi are fighting related.

thanks, but read most of those.

Only 4 chapters out, but Teppu looks rather promising.

realistic fightings?
-> Shigurui

Dangu? Best damn fighting manga I've read recently.
