Try Route 11. Its to the right from Vermillion City.
if your pokemon is level 45 and over and you would like to train it go to the elite four and get to the guy or girl your pokemon is super effective on then battle it .
it depends on what Pokemon you like to train or breed the most.but in my personal opinion i would choose shuckle
I would like to know...
train like heck
you can train it at some weak places like where you start your adventure or you can let it hold a exp.share and fight pokemon with another pokemon in your party.
Train them by defeating the Pokémon League over and over again.
Your training for the E4? I would say Victory Road. Train to about level 47 there. Use exp. shares for Pokemon weak to rock types, like flying or fire. The champion has a level 50 Pokemon, and that's their strongest.
Personally, I would train a Bird-Type Pokemon at a place where those types of Pokemon is very effective to it. Like Fighting-Types. They are weak to Bird-Types. So, I would train it there!
have your back up Pokemon be like sabley or you can just train your Pokemon A LOT
You just train it lots and gradually over time it will begin to like you
train like any other game
to get Pokemon to like you you just train them and give them poffins and if they let you walk them in amity square
