I recommend weak hero. Not really exactly a long those lines but Although they main character gets beaten up, later become stronger. He too also gets into fights and doesn;t want to e a weakling. So he trained and stuff.

Reminding myself I need to read these :>
Looking for a manga about a student, he always gets into fights or gets bully but he doesn't want to be a weakling anymore and paid a fee to some man to be his teacher for fight. The student was able to become of a goood fighter due to his eye sight; taking his glasses off.
