One. battle all the trainers you haven't battled and dodged. Two. if you've done the first option use exp share and keep on battling the Pokemon league that's what I did. Three. if you cant do any of the above im stumped, I really can't think of anything else
Victory road will be a good place to rhydons lv 41-43 give about 1200 xp and steelixs about 1100 xp. Golbats give about a 1000 xp so you can easily train there and if you use a Pokemon again and again in while battling the Pokemon league and its about lv65, it should gain a decent 2 to 4 levels through the Pokemon league.
The best place to train a Pokemon that is between levels 20 and 30 in Pokemon Ruby Version is between Mauville City and Fortree City.
Probably just keep challenging the Pokemon league because the keep getting consecutively stronger every time you challenge them
any wild grass or the battle tower
in diamond and pearl and platinum you can choose chimchar as your starter Pokemon and if you train it to level 16 it will become a monferno.
train your Pokemon alot. i got all of my Pokemon to level 18 before the first gym because i trained them alot.
Well that is a hard question. It all depends on the level of your pokemon. To train level 25-30 pokemon the best place is Desert Resort. Another place that is good is Cold Storage.
a wingull will evolve at level 25 in Pokemon platinum, so just train it one more level for it to level up, unless you're keeping it as it is to learn moves at a faster rate.
Train them............
route 205 for Pokemon diamond, pearl and platinum. the trainers have Pokemon from level 10 to level 17
Train it to Level 30
Train it to level 45.
You train your Pokemon to lvl 100 or you can find some at the battle frontier in the place where you rent Pokemon and select open level in Pokemon platinum
anywhere.
Some people will argue with me but i think the best place to train is at the Pokemon lugue you can battle them over and over again
There are various good places to train flying types in Pokemon Platinum. A good thing to do would be to use the vs seeker.
The best place to level up any Pokemon is the Pokemon league.By fighting the elite four at the Pokemon league your Pokemon will level up realy fast.If you have a low level Pokemon,give it an exp share and make a more powerfull Pokemon battle.
At the Pokemon league.
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!
find a place that has wild Pokemon the same level as it.
in heart gold cerulean cave in platinum i don't know
