i am searching for a manga about martial arts or street fighting where the main character is weak but becomes stronger.

preferrably like
Change Guy
Angel Densetsu

This is my Siggie.

Veritas
Tenjou Tenge
Shijou Saikyou no Deshi Kenichi

A loose mouth is indicative of an empty brain.

the breaker

The GaGa Law: (RAH)² (AH)³ + RO (MA + MAMA) + (GA)² + OOH(LA)² = Bad Romance

You should read History's Strongest Disciple Kenichi then, it fits your description perfectly and the same can be said about Holyland. Both feature a normal guy who become strong as he learned more about martial arts. 😎

I think there's more but those two seems a perfect fit 🙂

You like the things that i HATE, and i HATE the things that you like

Definitely recommend Holyland.
If you want a rather light comedy manga then try Full Contact
