Hello everyone, I fought yesterday in an amateur bout.My opponent was weak and I felt that I would crush him. a couple of minutes I beat him a little bit then my legs felt tired and heavy.I barely finish the first round and staying up.Second round I messed up.I don't think I have breathing problem because I did a lot of road works.I'm from Turkey and fights happens occasionally.Probably I fought 9,10 months before this fight.With this fight I did my sixth fight.I was wondering what can I do to prevent this situation and what training should I focus on.Thank you for every advice I appericiate it.
note : my age is 25 probably I can do this sport as a fighter a couple of years and don't wanna quit it like this and before I quit I want to accomplish something.
