Get the exp.share,give it to the Pokemon you want to level up and beat the Pokemon league but once you get it at a certain level for example i got my charizard to level 59 and then stock up on some healing supplies and a few Pokemon so if your Pokemon your trying to train faints send out the other Pokemon and heal the one that just fainted. but this might take a while but this actually worked for me. good luck!

well my way is say you just beat the electric gym and the wild Pokemon are like lvl 15 or higher put like a lvl 1-10 in fighting but before you attack hit the Pokemon button and get out your BEST Pokemon out and kill the lvl 15 or so and get like 150XP+ which will probabily lvl the low lvl Pokemon a few times
