I think that since Saitama never concider being a hero as trainning since he considers it a hobby. Saitama stated hes been doing the hero thing for 3 years. What do heros do in the one punch man univers they fight monsters. So for 3 years Saitama was the unnamed hero defeateing the villains by himself. So i believe he started with low level villians and worked his way up to tiger demon, dragon , and eventaully to God. With each fight superpassing his limit. Look at how he is with genos he always lets him fight first. WIth each fight you can see genos getting stronger and stronger surpassing his limit with each fight. The one punch man story is pretty much the after math of him defeating a God level villian.
